What is anxiety?
Anxiety is a feeling of unease, worry or fear. It is a normal part of being human — everyone feels anxious sometimes, such as before an exam or a big decision. It becomes something worth addressing when it is frequent, feels overwhelming or hard to control, and begins to affect your everyday life.
How it can feel
Anxiety affects the mind and the body. You might notice:
- constant or excessive worrying
- feeling tense, restless or on edge
- difficulty concentrating or sleeping
- a racing heartbeat, sweating, or a churning stomach
- tiredness and irritability
Everyone experiences it differently, and there is no “right” way for it to feel.
What can help
There is a lot that helps, and you do not have to manage it alone:
- Self-help — regular physical activity, good sleep habits, breathing and relaxation techniques, and cutting down on caffeine and alcohol.
- Talking therapies — such as cognitive behavioural therapy (CBT), which is effective for anxiety and available through the NHS.
- Medication — sometimes helpful, and something a GP can discuss with you.
Getting support
If anxiety is affecting your life, talking to a GP is a good step — they can explain the options and help you access support. Anxiety is common and treatable, and reaching out is a sign of strength, not weakness.

Common questions about anxiety
- What does anxiety feel like?
- Anxiety can cause emotional symptoms such as constant worry, feeling on edge or struggling to concentrate, and physical symptoms such as a racing heart, sweating, a churning stomach, tiredness and trouble sleeping. It affects people differently.
- When does anxiety become a problem?
- Some anxiety is normal and even useful. It becomes something to address when it is frequent or intense, feels hard to control, or starts to interfere with everyday life — your work, sleep, relationships or enjoyment of things.
- What helps with anxiety?
- Many people are helped by self-help approaches (such as regular exercise, good sleep, breathing techniques and reducing caffeine and alcohol), talking therapies like CBT, and sometimes medication. A GP can help you find the right combination.
- Can anxiety be treated?
- Yes. Anxiety is very common and treatable. Most people improve with the right support, whether that is self-help, talking therapy, medication, or a combination. Reaching out is the first step.
- What is the best treatment for anxiety?
- For most anxiety problems, cognitive behavioural therapy (CBT) has the strongest evidence and is recommended by NICE. Self-help, regular exercise and lifestyle changes help too, and some people are offered medication such as an SSRI antidepressant. In England you can refer yourself to NHS Talking Therapies without a GP. The best approach depends on the type and severity of your anxiety.
- Is there a best vitamin or supplement for stress and anxiety?
- No supplement is proven to treat anxiety, and supplements are not a substitute for proven treatments or getting help. A balanced diet usually provides what you need. Low vitamin D or B12 can affect mood, so a GP may test for these if you have symptoms. Check with a pharmacist or GP before taking high-dose supplements, as some interact with medicines.
- What is the best medication for anxiety?
- There is no single best medicine, and mood stabilisers are not a standard treatment for anxiety despite being a common search. The usual first-choice medicines are SSRI antidepressants such as sertraline, which treat anxiety as well as depression. Beta-blockers can ease physical symptoms short-term. A GP will weigh up the options with you, usually alongside talking therapy.
- Is there a free anxiety test?
- The GAD-7 is a short, validated questionnaire widely used to measure anxiety, and the NHS offers a free mood self-assessment online. These can help you describe your symptoms but do not give a diagnosis. If your score is high, or anxiety is affecting your life, see a GP or refer yourself to NHS Talking Therapies.
