- Treated online: Yes, usually. Anxious feelings and the anxiety disorders behind them are assessed and treated by video; a first episode of chest pain, breathlessness or an irregular heartbeat needs emergency care first.
- What anxiety does: stress hormones, such as adrenaline and cortisol, cause physical symptoms: a faster heartbeat, sweating, dizziness, breathlessness and a churning stomach.
- How common: anxiety disorders are the world’s most common mental disorders, affecting 470 million people in 2023, more women than men.
- Treatment works: talking therapies, usually cognitive behavioural therapy (CBT), come first; an antidepressant called an SSRI can also help.
- Emergency: call 112 for sudden chest pain that does not go away or spreads to the arm, neck, jaw, stomach or back, or for thoughts of ending your life that you might act on.
Do not book a video appointment for sudden chest pain or pressure that does not go away, chest pain that spreads to the arm, neck, jaw, stomach or back, palpitations with chest pain, breathlessness or fainting, or a first episode of severe breathlessness. Call 112 or go to an emergency department, so a heart or lung problem is ruled out before anyone calls it anxiety. If you are thinking about ending your life, or feel you cannot keep yourself safe, call 112.
Can an online doctor treat anxious feelings?
Yes, usually. Anxiety is recognised from how it feels and how it affects your life, so a doctor can assess it by video, look for physical causes and triggers such as caffeine, alcohol, medicines or an overactive thyroid, and treat it with self-help, a referral for talking therapy and, when it is right for you, medicine. A first episode of chest pain, breathlessness or an irregular heartbeat needs emergency care first, and some anxiety disorders also need specialist therapy in person.
How an online consultation helps with anxious feelings
- Physical causes ruled out: Heart, lung and thyroid problems, low blood sugar and medicines are considered before anxiety is named.
- Your symptoms explained: What adrenaline does in your body, so a racing heart or a tight chest feels less frightening.
- A plan that works: Breathing and self-help that work, a referral for talking therapy, and medicine when it is right.
- The right diagnosis: Whether it is generalised anxiety, panic, social anxiety, health anxiety or something else, and what helps each.
What the doctor checks in an online consultation about anxious feelings
The doctor checks the warning signs first, then how the anxiety feels and what drives it. The doctor asks about:
- Warning signs: chest pain, breathlessness, fainting, palpitations that do not stop, and thoughts of harming yourself.
- How it feels: your physical symptoms, your thoughts and worries, sudden attacks of panic, and what you avoid.
- When it started and how long it lasts: a recent event or stress, or anxiety that has been there most days for months.
- Triggers: caffeine, energy drinks, alcohol and hangovers, recreational drugs, and new or stopped medicines.
- Your health: thyroid problems, asthma, heart conditions, pregnancy or the menopause, sleep and mood.
Before the call, note your main symptoms, when they happen and what makes them better or worse. Saying ‘I feel anxious all the time and I want help’ is enough to start.
What are the symptoms of anxiety?
Anxiety is a feeling of stress, panic or fear, and it affects the body as much as the mind. Everyone feels anxious at times, before an exam, a flight or a hard conversation. The symptoms are the same when anxiety becomes a problem; the difference is how often they come, how long they stay and how much they affect your life:
Swipe sideways to compare →
| Where it shows | Common symptoms |
|---|---|
| Mind | Feeling tense, nervous or unable to relax, worrying about the past or the future, racing thoughts, fearing the worst, a sense of dread, irritability, difficulty concentrating |
| Heart and chest | A faster, irregular or more noticeable heartbeat, chest pains, breathlessness |
| Head | Light-headedness, dizziness, headaches |
| Stomach | Loss of appetite, indigestion, stomach cramps, bloating, nausea, constipation or diarrhoea |
| Body | Sweating, shaking, feeling hot, a dry mouth, tiredness |
| Sleep | Trouble falling or staying asleep |
| Behaviour | Avoiding places and situations that make you anxious, difficulty looking after yourself, not enjoying your free time, struggling with relationships, checking things again and again |
Why does anxiety cause physical symptoms?
When you feel anxious or scared, your body releases stress hormones, such as adrenaline and cortisol. They prepare the body to act: the heart beats faster, you sweat more and you breathe faster. That helps in real danger, but when the alarm goes off without one, the same changes feel like illness, and in some people they set off a panic attack. The symptoms are real, not imagined.
What does a panic attack feel like?
A panic attack is a sudden rush of intense fear with strong physical symptoms: a racing heartbeat, feeling faint, sweating, trembling, shortness of breath, chest pain, a choking feeling, tingling in the fingers or lips, nausea, and feeling that you are losing control or are not connected to your body. Most panic attacks last between 5 and 20 minutes. They are frightening, but they are not dangerous. See panic attacks.
Is it anxiety or something else? Anxiety symptoms in the body
Most physical symptoms of anxiety have look-alikes, and a doctor rules those out before calling a symptom anxiety. Where you feel it, and what comes with it, decides what to do:
Swipe sideways to compare →
| Where you feel it | How anxiety can feel | Other possible causes | When to get help |
|---|---|---|---|
| Chest | Tightness or a sharp pain, often with a fast heartbeat, sweating or dizziness, set off by worry | A heart attack or angina, a lung problem, indigestion | Call 112 for sudden chest pain that does not go away, spreads to the arm, neck, jaw, stomach or back, or comes with sweating, sickness, light-headedness or breathlessness. See chest pain |
| Heart | A racing, pounding or fluttering heartbeat (palpitations) | Caffeine, alcohol, nicotine, medicines, an overactive thyroid, anaemia, the menopause, a heart rhythm problem | Call 112 if palpitations do not go away or come with chest pain, breathlessness or fainting. See heart palpitations |
| Breathing | Breathing fast, feeling you cannot get enough air, a choking feeling | Asthma, a chest infection, anaemia | Call 112 for severe breathlessness, especially the first time |
| Head | Light-headedness, dizziness, headaches | Dehydration, low blood sugar, an inner-ear problem, migraine | See dizziness; call 112 for dizziness with chest pain or fainting |
| Stomach | Butterflies, nausea, cramps, needing the toilet, loss of appetite | IBS, indigestion, a stomach bug | See stomach pain |
| Skin and hands | Sweating, shaking, hot flushes, tingling in the fingers or lips | An overactive thyroid, the menopause, low blood sugar, alcohol withdrawal | See a doctor if it keeps happening |
| Sleep and energy | Trouble sleeping, waking with a racing mind, tiredness | Insomnia, depression | See a doctor if it lasts a few weeks |
| Feeling unreal | Feeling detached from your body or your surroundings | Depersonalisation and derealisation | See a doctor if it keeps happening |
Palpitations that keep coming back, happen more often or last longer than a few minutes need a doctor, even when you feel well, and so do palpitations if you have a heart condition or heart problems run in your family.
Why do I feel anxious for no reason?
Anxiety does not always have an obvious trigger, and there is usually more than one cause. When you feel anxious without knowing why, these are the common hidden drivers:
- An anxiety disorder: in generalised anxiety disorder, you feel anxious a lot of the time, about many things, and the worry is hard to control. It is more likely to be generalised anxiety disorder if you have felt anxious most of the time for at least 6 months.
- Caffeine, alcohol and drugs: caffeine can make anxiety worse, alcohol and recreational drugs can cause it, and anxiety can be a side effect of some medicines, or come on when you stop them.
- Your body: an overactive thyroid causes nervousness, anxiety and irritability, and palpitations from any cause can feel like fear.
- Hormones: the menopause can make you irritable, stressed and anxious, and anxiety that returns before each period can be PMDD.
- Past and present stress: very stressful or traumatic experiences, money, housing or work problems, illness and bereavement can all leave you anxious long after the event.
- Other conditions: anxiety can be part of PTSD, depression or OCD, and autistic people and people with ADHD are more likely to have anxiety.
Finding the driver changes the plan: cutting caffeine, treating a thyroid problem or getting help for low mood can ease anxiety that seemed to come from nowhere.
What is hangxiety? Anxiety after drinking
Hangxiety is the anxiety, and sometimes low mood, that some people feel the morning after drinking. Alcohol calms at first, but heavy drinking leaves you dehydrated, with disturbed sleep and low blood sugar, and many people also worry about what they said or did. Small amounts of alcohol stimulate a calming brain chemical called GABA; heavy drinking depletes it, which adds tension and panic as the alcohol wears off.
- Hangxiety is a particular problem for people with social anxiety, and for people who are anxious already.
- Drinking again to feel better, the ‘hair of the dog’, restarts the cycle: anxiety comes back as the alcohol wears off.
- Rest and water help the morning after, and breathing exercises help the anxiety.
- Keeping to no more than 14 units a week, spread over 3 or more days, with drink-free days, lowers the risk, and not drinking avoids it.
- Anxiety often eases within a couple of weeks of cutting down or stopping, as sleep improves.
If you drink heavily every day, or get shaky, sweaty or anxious when you stop, do not stop suddenly: withdrawal can be dangerous and needs medical advice. See substance abuse.
When are anxious feelings an anxiety disorder?
Anxious feelings become a disorder when they are out of proportion, hard to control, last for months, or affect your work, relationships or daily life. Each anxiety disorder has its own pattern, and its own page:
Swipe sideways to compare →
| Condition | What it usually feels like | Online care |
|---|---|---|
| Generalised anxiety disorder | Worry about many things, most days, that is hard to control | Treated online |
| Panic attacks and panic disorder | Sudden attacks of intense fear, and dread of the next one | Treated online |
| Social anxiety | Fear of being judged, embarrassed or watched | Treated online |
| Health anxiety | Constant worry about being ill, checking your body and seeking reassurance | Treated online |
| Phobias | Overwhelming fear of a specific object, place, animal or situation | Treated online |
| Agoraphobia | Fear of places where escape or help feels hard, and avoiding them | Treated online |
| PTSD | Reliving a traumatic event, with nightmares, flashbacks and feeling on guard | Partly online |
| OCD | Unwanted, distressing thoughts and the urge to repeat actions to ease them | Treated online |
| Stress | Pressure that has stopped switching off, with tension, poor sleep and irritability | Treated online |
| Depression | Low mood and loss of interest, often with anxiety alongside | Treated online |
Anxiety disorders are common, and they are treatable. Worldwide, only about 1 in 4 people who need treatment get any, so asking for help is worth it.
How can I stop feeling anxious right now?
These steps calm the body’s alarm. They work best when you practise them daily, not only in a crisis:
- Let your breath flow deep down into your belly, without forcing it, breathing in through your nose and out through your mouth.
- Breathe in gently, counting steadily from 1 to 5, then breathe out gently, counting from 1 to 5 again.
- Keep going for at least 5 minutes, and make it part of your daily routine.
In a panic attack, stay where you are if you can, breathe slowly and deeply, and remind yourself that the attack will pass and is not life-threatening.
How to stop being anxious in the longer term
- Talk to a friend, a family member or a health professional about how you feel.
- Exercise regularly, such as running, walking, swimming or yoga, and eat regular meals.
- Set small, achievable targets rather than trying to do everything at once.
- Gradually spend more time in situations that make you anxious, rather than avoiding them.
- Cut down on caffeine, and do not use alcohol, cigarettes, gambling or drugs to relieve anxiety.
Which treatment for anxious feelings might the doctor recommend?
Treatment follows the cause and how much the anxiety affects your life. This is the framework the doctors use, in line with NHS guidance:
Swipe sideways to compare →
| What you have | Likely first step | Suitable for online care? | When in-person care is needed |
|---|---|---|---|
| Worry most days for months, hard to control | Self-help and a referral for talking therapy, usually CBT; medicine if it is right for you | Yes | Rarely; specialist care if treatment does not help |
| Panic attacks that keep coming back | Explanation, a plan for attacks, and a referral for CBT | Yes | Call 112 for a first episode of chest pain or breathlessness |
| Fear of social situations, or of illness | Assessment and a referral for CBT | Yes | For face-to-face therapy if needed |
| Anxiety after a traumatic event, with flashbacks | Assessment and a referral for trauma-focused therapy | Partly | For trauma-focused therapy |
| Anxiety with palpitations, restlessness or muscle weakness | A thyroid blood test | Yes, to assess | For the blood test; call 112 for palpitations with chest pain or fainting |
| Anxiety the morning after drinking | Advice on alcohol and anxiety | Yes | If you drink heavily every day: get advice before you stop |
| Anxiety with low mood or loss of interest | Assessment for depression and a treatment plan | Yes | Call 112 for thoughts of ending your life that you might act on |
| Sudden chest pain, or palpitations with fainting or breathlessness | Emergency care | No | Call 112 now |
Not sure whether it is anxiety? A doctor can help you work it out in one consultation.
See available times →Treatment options for anxious feelings
What you can do yourself
- Practise slow breathing every day, so it works when you need it.
- Use recommended self-help, such as books, online tools or courses you can do in your own time.
- Keep moving, eat regular meals and keep regular sleep times.
- Cut down on caffeine and alcohol, and keep away from recreational drugs.
- Face what you avoid in small steps, rather than all at once.
Prescription treatment
A prescription is never issued without a consultation. Talking therapies usually come first, most often CBT, either one to one or in a group. If medicine is right for you, the doctor may prescribe an antidepressant, usually a type called an SSRI, after a full assessment and with follow-up. It usually takes 1 to 2 weeks to start working and up to 8 weeks to work fully, and it should never be stopped suddenly. Benzodiazepines are generally not recommended for anxiety disorders because of the risk of dependence, and benzodiazepines, pregabalin and other controlled medicines are never prescribed online. If the doctor prescribes, use the prescription at a pharmacy near you.
What does not help
Alcohol, cigarettes or drugs to calm down: the anxiety comes back worse. Avoiding everything that makes you anxious, which makes the fear grow. Focusing on what you cannot change.
Special situations
Pregnancy and after birth
Tell your midwife or doctor about anxiety in pregnancy or after birth, because it can be treated, and see depression in pregnancy and after birth.
Menopause
The menopause can make you feel irritable, stressed and anxious, and hot flushes can bring palpitations and anxiety. Treatment for the menopause often helps: see menopause.
Heart, lung and thyroid conditions
If you have a heart or lung condition or a thyroid problem, new or different symptoms should be checked before they are put down to anxiety. The doctor also checks how any anxiety medicine fits with the medicines you already take.
While travelling in Europe
Travel can stir up anxiety, from a fear of flying to panic far from home. A doctor by video can help wherever you are, and the phobias page covers fear of flying. In an emergency, call 112 anywhere in the EU.
Children
Mobi Doctor consultations are for adults aged 18 and over. A child who is unwell needs a paediatrician or a local doctor in person, and emergency signs in a child mean 112.
When anxious feelings are treated online, and when you need in-person care
Treated online: anxious feelings and worry, generalised anxiety, panic attacks, social and health anxiety, phobias, hangxiety, a referral for talking therapy, and treatment with an SSRI when it is right for you.
In-person care: a first episode of chest pain, breathlessness or an irregular heartbeat, blood tests, face-to-face or trauma-focused therapy, specialist mental health care, and any emergency.
When to get in-person care
Call 112 or go to an emergency department now for:
- sudden chest pain or pressure that does not go away

Frequently asked questions about anxious feelings
What are the symptoms of anxiety?
Feeling tense, nervous or unable to relax, worrying, fearing the worst and finding it hard to concentrate, with physical symptoms such as a fast or irregular heartbeat, dizziness, sweating, shaking, breathlessness, headaches, nausea and trouble sleeping.
Why do I feel anxious for no reason?
Anxiety does not always have an obvious trigger. Generalised anxiety disorder, caffeine, alcohol, drugs, some medicines, an overactive thyroid, the menopause and past stress can all cause it. A doctor can help find the driver.
How do I stop feeling anxious?
To stop feeling anxious right now, breathe slowly in through your nose and out through your mouth, counting to 5 each way, for at least 5 minutes. In the longer term, talk to someone, exercise, cut down on caffeine and alcohol, and face what you avoid in small steps.
What is hangxiety?
Hangxiety is the anxiety some people feel the morning after drinking. Dehydration, poor sleep, low blood sugar and the brain’s chemistry rebalancing all play a part. It is a particular problem for people with social anxiety.
Can anxiety cause real physical symptoms?
Yes. Anxiety releases stress hormones, such as adrenaline and cortisol, which cause a faster heartbeat, sweating, dizziness and a churning stomach. The symptoms are real, not imagined, including in health anxiety.
How do I know if it is anxiety or my heart?
You cannot be sure on your own. Call 112 for sudden chest pain that does not go away, chest pain that spreads to the arm, neck, jaw, stomach or back, or palpitations with chest pain, breathlessness or fainting. Anxiety is diagnosed once these are ruled out.
How long does a panic attack last?
Most panic attacks last between 5 and 20 minutes, and some have been reported to last up to an hour. They are frightening, but they are not dangerous and they always pass.
When does anxiety become a disorder?
When it is out of proportion, hard to control, lasts for months or affects your daily life. It is more likely to be generalised anxiety disorder if you have felt anxious most of the time for at least 6 months.
What can I do at home to calm anxious feelings?
Slow breathing, in through the nose and out through the mouth for a count of 5 each way, calms the body; so does moving, since a brisk walk or a run burns off adrenaline. Cut down on caffeine and alcohol, keep regular sleep, eat regularly, write worries down and set a fixed worry time, and face the situations you avoid in small steps rather than retreating from them. Anxious feelings that keep returning for weeks are worth a consultation, because treatment works.
Can anxious feelings be prevented?
Not entirely, because anxiety is a normal response, but you can make anxious feelings less frequent and less intense: regular exercise, enough sleep, less caffeine and alcohol, time outdoors and keeping in touch with people all protect against it, and learning the skills of cognitive behavioural therapy early, from a course, an app or a therapist, lowers the chance that everyday worry grows into a disorder. Treating a first episode properly, rather than waiting it out, also makes a return less likely.
Can caffeine or alcohol make anxiety worse?
Yes. Caffeine can make anxiety worse, and heavy drinking increases tension and panic as the alcohol wears off. Anxiety often eases within a couple of weeks of cutting down.
Can an online doctor prescribe medicine for anxiety?
Yes, when it is right for you. After a full assessment of your anxiety, the doctor may prescribe an antidepressant called an SSRI, with follow-up. Benzodiazepines, pregabalin and other controlled medicines are never prescribed online.
Can an online doctor treat anxious feelings?
Yes, usually. A doctor can assess anxiety by video, rule out physical causes, and treat it with self-help, a referral for talking therapy and medicine when it is right. Chest pain or breathlessness for the first time needs emergency care first.
