Why does anxiety often get worse in your twenties and thirties?

This decade tends to bring several big, uncertain decisions at once, career, money, relationships, whether to have children, which keeps the nervous system on alert. Generalised anxiety, panic and health anxiety also commonly first appear or become harder to manage during this period.

Is CBT effective for anxiety in this age group?

Yes. Cognitive behavioural therapy is a first-line, NICE-recommended treatment for generalised anxiety disorder and panic disorder, and it works by changing the thoughts and behaviours, such as avoidance and reassurance-seeking, that keep anxiety going.

What is the difference between ordinary worry and generalised anxiety disorder?

Occasional worry is a normal response to real pressures and usually settles once the situation resolves. Generalised anxiety disorder involves worry that is present most days for several weeks and starts to stop you doing things, such as work, socialising or appointments.

Can sleep and lifestyle changes help without therapy?

They support therapy rather than replace it for anxiety that is already established. Poor sleep, high caffeine or alcohol intake, and heavy time spent on comparison or symptom-checking online all tend to keep anxious thinking active, so addressing them makes other treatment work better.

What is the difference between CBT and ACT for anxiety?

CBT works by identifying and testing the specific thoughts and behaviours maintaining anxiety. ACT takes a different approach, helping you keep acting in line with what matters to you even while anxious thoughts are present, rather than trying to argue yourself out of them.

Do you offer online therapy for anxiety in Brighton and East Sussex?

Yes. We are clinical psychologists for Brighton and East Sussex, working online with adults, so assessment and therapy both happen over video call regardless of whether you are near the seafront, in Hove, Kemptown or further out towards Portslade.

Anxiety in your twenties and thirties: what actually helps

Anxiety in your twenties and thirties often responds well to a mix of structured therapy, changes to daily habits, and a clearer understanding of what is driving it. Cognitive behavioural therapy (CBT) has good evidence for generalised anxiety and panic, and small, consistent changes to sleep and routine tend to support whatever therapy you choose.

Why this decade feels different

Your twenties and thirties tend to stack decisions on top of each other: career direction, money, relationships, whether and when to have children, where to live. Any one of these would be enough to raise anxiety on its own. Together, and often without a settled home life or a fixed income to fall back on, they can keep the nervous system on alert for years at a time.

This is also the period when generalised anxiety disorder, panic disorder, social anxiety and health anxiety most commonly first appear or become harder to manage. That timing is not a coincidence. The brain’s threat-detection system responds to uncertainty and to a sense of things being high stakes, and this decade tends to supply both in steady supply.

Common triggers people bring to therapy

A few patterns come up repeatedly in clinical work with people in this age group. Starting a demanding job, or losing confidence in one you already have. Comparing your life stage to friends or people online, particularly around property, relationships or children. Health scares, including ordinary symptoms that get catastrophised after a search online. And the general sense of needing to have things figured out by a certain age, which rarely matches how life actually unfolds.

What actually helps

Cognitive behavioural therapy (CBT)

CBT is a first-line, NICE-recommended treatment for generalised anxiety disorder and panic disorder. It works by identifying the specific thoughts and behaviours that keep anxiety going, such as avoidance, checking, or reassurance-seeking, and then testing them out systematically. Rather than simply talking about anxiety, CBT gives you a structured way to change your relationship with it: a formulation of what is maintaining the problem, and a set of skills you practise between sessions.

For panic disorder specifically, CBT often includes work on the physical sensations of panic, since a lot of the fear comes from misreading normal bodily signals, a fast heartbeat, dizziness, breathlessness, as dangerous. Learning to interpret those sensations accurately, and to stop the avoidance that panic encourages, is usually more effective long term than trying to suppress the sensations themselves.

Acceptance and commitment therapy (ACT)

ACT takes a different route to a similar outcome. Instead of challenging anxious thoughts directly, it focuses on changing how much control those thoughts have over your behaviour. The aim is to keep acting in line with what matters to you, a relationship, a piece of work, a decision, even while anxious thoughts are present. For people whose anxiety centres on big life decisions rather than a single fear, this can feel more workable than trying to argue yourself out of every worry.

Practical daily changes

Therapy tends to work better alongside a few basic changes, and worse without them. Sleep is the biggest lever: chronic short sleep lowers the threshold for anxiety and makes it harder to use the skills learned in therapy. Reducing caffeine and alcohol, both of which affect anxiety and sleep more than most people expect, is a second one. Regular movement, even brief walks, has a measurable effect on anxiety symptoms, and it does not need to be intense to help.

Beyond the physical basics, deliberately narrowing how much time you spend on comparison, whether that is scrolling other people’s milestones or checking symptoms online, reduces one of the main things keeping anxious thinking active. None of this replaces therapy for anxiety that is already established, but it changes how much work the therapy has to do.

When to seek support

Occasional worry is ordinary and does not need treatment. It is worth getting an assessment when anxiety is present most days for several weeks, when it is stopping you doing things you would otherwise do, turning down work, avoiding social plans, cancelling appointments, or when physical symptoms such as a racing heart or breathlessness are frequent enough to worry you separately from the anxiety itself. A psychologist can help you work out whether what you are experiencing fits a specific pattern, such as generalised anxiety or panic, or is better understood as a response to a specific set of pressures.

If you are having thoughts of harming yourself, contact your GP, call 111, or in an emergency call 999 or go to your nearest A&E.

Getting started online in Brighton and East Sussex

We are clinical psychologists for Brighton and East Sussex, working online with adults, so an assessment and any therapy that follows happens over video call rather than in a waiting room. That suits people managing anxiety particularly well: no unfamiliar building to walk into, no commute added to an already full week, and the option to have sessions from home, work, or wherever is easiest that day. It also means location within the area, whether you are near the seafront, up in Hanover or Preston Park, or out towards Hove and Portslade, makes no practical difference to how quickly you can be seen or how the work is done.

An initial assessment covers what is happening, how long it has been going on, and what has helped or not helped before, and from that a psychologist will suggest an approach, usually CBT or ACT, based on what is likely to fit best. We will update this site as the practice develops.
