High-functioning anxiety: signs, causes and what helps

What is high-functioning anxiety?

People often describe it as looking fine on the outside and feeling exhausted on the inside. Anxiety disorders involve “more than occasional worry or fear”^[3], so the useful question is not whether you are still coping, but how much the worry is costing you.

Is high-functioning anxiety a disorder?

Not on its own, but it can be a sign of one. The WHO’s description of generalised anxiety disorder (GAD) says the symptoms cause significant distress or get in the way of daily life, and adds: “If functioning is maintained, it is only through significant additional effort”^[2]. In other words, keeping up at work does not rule GAD out.

In the UK, a GP may diagnose GAD if worry affects your daily life, is hard to control, and you have felt anxious a lot of the time for at least 6 months^[4]. Many people with an anxiety disorder are not severely held back by it: in a national US survey, about 4 in 10 adults with an anxiety disorder had only mild impairment^[5]. And anxiety that falls just short of a diagnosis is about twice as common as GAD itself, and can still cause real suffering at work and at home^[6]. Only a qualified professional can assess which applies to you.

Signs of high-functioning anxiety

Signs doctors look for

• Worry that affects your daily life and is hard to control^[7]
• Feeling restless, irritable, tense or tired easily, and finding it hard to concentrate^[7]
• Trouble sleeping^[7]
• Physical signs such as stomach problems, a noticeable heartbeat, headaches or muscle aches^[7][9]
• Habits that keep the worry down: over-preparing, putting things off, or needing reassurance. The WHO notes avoidance, reassurance-seeking and procrastination as ways people try to reduce worry^[2]

Things people often describe

These are not on official symptom lists, but people who call their anxiety “high-functioning” often mention them: finding it hard to say no, not being able to rest without feeling guilty, feeling like a fraud despite doing well, and replaying conversations afterwards. If you notice these, our posts on how to stop overthinking may help.

Anxiety can cause real physical symptoms, but so can other health problems. If you have physical symptoms, see a doctor first to rule out other causes, such as thyroid problems or the effects of caffeine or medicines^[1][2].

Is there a high-functioning anxiety test?

No validated test exists, because high-functioning anxiety is not a defined condition. Doctors often use a short questionnaire called the GAD-7, seven questions about the last two weeks, to screen for generalised anxiety and how severe it is^[10]. A screening score can tell you whether to talk to a professional, but it cannot diagnose you; a GP or therapist will ask about your worries and physical symptoms^[4]. Bliss Therapy also has a free anxiety self-test.

Why can you be anxious and still perform well?

Research suggests anxiety makes thinking less efficient, but people often keep their results up by working harder: putting in more effort and attention^[11]. On average, anxiety is linked with poorer performance on working-memory tasks^[12], which is why doing well can feel so tiring.

Two patterns often sit behind this kind of anxiety. Perfectionism is linked with anxiety and other mental health problems^[15]; the parts most linked over time are fear of making mistakes and doubting your own actions, though the effects are small^[16]. Finding uncertainty hard to tolerate is also clearly linked with worry and anxiety^[17].

The hidden costs: burnout and sleep

Anxiety and burnout often go together, but research has not shown which one causes the other^[18]. Burnout is a work-related state, “not classified as a medical condition”^[19]. The fear-of-mistakes side of perfectionism is more strongly linked with burnout than having high standards^[21]. Anxiety and poor sleep also seem to feed each other^[20]. If you are exhausted from work, see our page on therapy for work stress and burnout.

What helps with high-functioning anxiety?

Start with self-help

For milder anxiety, UK guidance suggests starting with self-help based on CBT, worked through over at least 6 weeks, and moving to more support if needed^[22]. The NHS suggests small daily habits: focusing on the present moment, setting a daily “worry time”, keeping a diary of when anxiety rises, and facing fears gradually, because avoiding things or relying on safety habits “might actually make our anxiety worse”^[8]. For high-functioning anxiety, that can mean practising doing less preparation than usual and seeing what happens. Regular physical activity can also help with anxiety^[31].

Therapy

CBT is the talking therapy the NHS usually offers for GAD^[23], and in trials, psychological treatment for GAD, mostly CBT, has helped much more than being on a waiting list^[24]. UK guidance offers either CBT or applied relaxation, usually 12 to 15 weekly one-hour sessions^[22]; for GAD, the two have worked about as well as each other^[25]. CBT aimed at perfectionism has also reduced anxiety in trials^[26].

Mindfulness can help too: in one large trial, an 8-week mindfulness course worked about as well as a standard anxiety medicine^[27], although a review found that kind of course less effective than CBT^[28]. Acceptance and commitment therapy (ACT) has shown effects similar to CBT, in fewer and smaller trials^[28][29].

Medication

Medication is also an option for GAD, usually an SSRI antidepressant, alone or alongside therapy^[23][30]. That is a decision to make with a doctor or psychiatrist.

On Bliss Therapy

UK guidance recommends offering therapy “in the preferred language of the person with GAD if possible”^[22]. On Bliss Therapy you choose a therapist who speaks your language, by video, with no waitlist. 52 psychologists and counsellors list anxiety and stress, with sessions from €30 (about £25); 42 of them list CBT and 11 list ACT.

Our therapists are based outside the UK and the US, so they are unlikely to be on UK registers or covered by US health insurance. Ask any therapist about their training and their registration in the country where they practise.

When to get help

Talk to a doctor or a therapist if worry is hard to control, has lasted for months, or is affecting your sleep, work, relationships or health, even if you are still coping. In the UK you can see a GP, or adults can refer themselves to NHS talking therapies^[35]. Anxiety disorders are the most common mental health conditions in the world^[30], but many people wait years before they first look for help^[32]. You do not need to wait until it gets worse.

High-functioning anxiety when you live abroad

Moving abroad can add its own pressure: the sense that the move has to be worth it, and being far from the people who know you best, can make anxiety easier to hide. Research on international students links the stress of adjusting to a new culture with more distress and depression^[33]. What people worry about can also differ between cultures^[2]. Language matters in care: in most studies of patients treated in their own language, at least one outcome was better^[34], which is why guidance recommends therapy in your preferred language where possible^[22].
