Anxiety, the guide that answers what to do next.

Key facts
Anxiety at a glance.
The essentials, in plain English — what it is, how common it is, and how it’s treated in the UK today.
-
What it is
Persistent worry or fear that interferes with daily life — beyond the anxiety everyone feels at times.
-
How common
Around 1 in 6 UK adults each week; more common in women.
-
Main types
Generalised anxiety disorder (GAD), panic disorder, social anxiety, health anxiety, phobias, OCD, PTSD.
-
Diagnosis
Clinical, using patterns and validated questionnaires like GAD-7. No blood test is needed unless another cause is suspected.
-
First-line treatment
CBT (self-help, group or one-to-one), plus an SSRI if medication is preferred or symptoms are severe.
-
Recovery
Most people improve significantly with treatment — and many recover fully.
Why this guide matters
A common problem — with treatments that work.
Anxiety is one of the most treatable conditions in medicine. The three points below shape everything else on this page.
-
Anxiety is treatable
Most people who reach for help improve significantly — many recover fully.
-
The right label matters
GAD, panic, social anxiety, OCD, PTSD — each has a distinct evidence-based treatment.
-
Help is available now
NHS Talking Therapies accept self-referral in most areas. See the red-flags section for crisis lines.
How the diagnosis is made
From first conversation to a clear plan.
The steps a UK GP will normally follow, in order — so you know what to expect and why.
Phase 1 · Recognising
Naming the pattern and scoring it
Phase 2 · Confirming
Excluding physical causes, choosing the type
Phase 3 · Managing
Stepped-care plan and review
- 01
Recognising
Persistent, disproportionate worry
Feeling on edge most days for weeks — not tied to a specific event, or wildly out of proportion to it.
- 02
Recognising
Impact on daily life
Sleep, work, relationships or activities being affected — that’s what makes it a disorder rather than everyday anxiety.
- 03
Recognising
Screening questionnaire
GAD-7 (for generalised anxiety) or PHQ-9 (for depression, often overlapping) — completed by you.
- 04
Confirming
Ruling out physical causes
Overactive thyroid, arrhythmia and some medications can mimic anxiety — a physical check and blood tests confirm.
- 05
Confirming
Which anxiety disorder
GAD, panic, social, OCD, PTSD or another — the treatment differs and getting the right label matters.
- 06
Managing
Stepped-care plan
Self-help and guided CBT for mild; formal CBT or SSRI for moderate; specialist input for severe or complex.
- 07
Managing
Review at 4–6 weeks
Adjustments to therapy or medication — both take time to work.
Typical timeline: 4–6 weeks from first appointment to a settled plan.
Symptoms
What anxiety actually feels like.
Anxiety shows up in the mind and the body. Here’s what to look for — and when to seek urgent help.
-
Persistent worry
Ongoing, hard-to-control worry about many things — a hallmark of generalised anxiety.
-
Panic attacks
Sudden intense fear with a racing heart, breathlessness, dizziness or chest tightness — peaking within minutes.
-
Muscle tension
Aches, tight shoulders, jaw pain, and general on-edge feeling.
-
Sleep problems
Difficulty getting off, waking early with racing thoughts, or feeling unrested.
-
Avoidance
Skipping situations, people or places to avoid the anxiety — which usually worsens it long-term.
-
Poor concentration
Racing or blank mind, difficulty finishing tasks or holding attention.
-
Physical symptoms
Palpitations, breathlessness, sweating, IBS-like tummy symptoms, headache — often disguised as physical illness.
-
When to seek urgent help
Thoughts of self-harm or suicide, or feeling you can’t keep yourself safe — see the red-flags section for support numbers.
Treatment
How anxiety is treated in the UK.
Talking therapies first, medication where it helps — what each option does, and when it fits.
-
Self-help CBT
Books, apps and online programmes based on CBT — a good first step for mild anxiety.
-
Guided self-help
CBT-based material with a therapist supporting you by phone or online — available on the NHS through Talking Therapies.
-
One-to-one CBT
12–20 sessions of face-to-face CBT is the gold-standard psychological treatment for most anxiety disorders.
-
SSRIs
Sertraline or escitalopram are first-line. Take 4–6 weeks to work; continue for at least 6–12 months after recovery.
-
SNRIs
Venlafaxine or duloxetine — second-line, useful when SSRIs aren’t tolerated or effective.
-
Beta-blockers
Propranolol taken before a specific situation reduces physical symptoms (tremor, palpitations). Not for daily use.
-
Lifestyle levers
Regular activity, moderate caffeine, sleep, and reduced alcohol all reduce baseline anxiety.
-
Specialist input
For severe, treatment-resistant or complex anxiety — referral to secondary care mental health services.

Red flags
When to reach out — and where.
These are the moments where anxiety needs prompt attention. If you are in crisis right now, the last item on this list has the numbers to call.
-
Thoughts of self-harm
Any thoughts of harming yourself — please reach out. Contact numbers are at the bottom of this list.
-
Suicidal thoughts or planning
Especially with intent or a plan — urgent help is available. See the numbers below.
-
Panic attacks daily
Frequent, disabling attacks — the picture usually responds well to treatment. Contact your GP.
-
Withdrawing from life
Stopping work, education or seeing people because of anxiety — deserves prompt review.
-
Using alcohol or drugs to cope
A common but risky strategy. Support exists — ask for it.
-
New severe anxiety in older age
Especially with physical symptoms — worth ruling out thyroid, cardiac and neurological causes.
-
Postnatal anxiety
Very common; effective treatment exists that’s safe in pregnancy and breastfeeding.
-
Rapid heart rate or chest pain
If new or severe — call 111 to be safe, even if you think it’s anxiety.
-
You are in crisis right now
Samaritans 116 123 (24/7, free). NHS 111 (mental health option). Text SHOUT to 85258. In an emergency, call 999 or attend A&E.
Living with it
Manageable, and often beatable.
Four things that make the biggest difference day to day — habits, approach, medication and reviews.
A quiet reminder
Consistency beats intensity, every time.
Small, steady changes — kept up for months — do more than a heroic week that doesn’t last.
- 01 Habits
Small, consistent changes
Regular movement, moderate caffeine, and going to bed at a similar time each night reduce baseline anxiety more than any one intervention.
- 02 Approach
Face it, don’t run from it
Avoidance feels helpful for hours; it makes anxiety louder for months. Gradual exposure is central to CBT.
- 03 Medication
Not a shortcut — a support
SSRIs work best with therapy. Take them for months, not days, and never stop abruptly.
- 04 Reviews
Check in with yourself
Symptom scores (GAD-7) every few weeks track progress and catch regression early.
Frequently asked
Everything we get asked about anxiety.
Quick answers on CBT, medication, self-referral and when to reach urgent help.
-
What counts as an anxiety disorder?
Anxiety that lasts for weeks, is out of proportion to the situation, and interferes with sleep, work, relationships or daily life — beyond the normal anxiety everyone feels.
-
Do I need a blood test?
Usually not. But thyroid tests and a physical check may be arranged to exclude an overactive thyroid, arrhythmia or another cause that can mimic anxiety.
-
CBT or medication first?
For mild-to-moderate anxiety, CBT is first-line. For severe anxiety, or by preference, an SSRI is offered. Combining both is often more effective than either alone.
-
Which SSRI is first-choice?
Sertraline and escitalopram have the best combination of effectiveness and tolerability for adults with anxiety. Others are chosen if needed.
-
How long before medication works?
4–6 weeks for the full effect. Sometimes anxiety worsens briefly in the first week or two — discuss this with your GP if it happens.
-
Are SSRIs addictive?
No — they don’t cause craving or dose escalation. Stopping suddenly can cause discontinuation symptoms, which is why the dose is tapered gradually.
-
Can I get NHS Talking Therapies without a GP?
Yes — most areas allow self-referral through NHS Talking Therapies (previously IAPT). Wait times vary by region.
-
Are beta-blockers safe for anxiety?
Propranolol taken occasionally before a specific stressful situation is safe for most people. It reduces physical symptoms — tremor, racing pulse — not the worry itself.
-
Is health anxiety different?
Yes — it’s a specific pattern of persistent fear of illness. A tailored version of CBT is highly effective.
-
When should I go to A&E?
If you are having thoughts of self-harm or suicide, or you can’t keep yourself safe. In the UK: 999, or attend A&E.
