High-functioning anxiety: why the people who look fine are often struggling most

What is high-functioning anxiety?

“High-functioning anxiety” is a phrase some people use for performance-driven worry that can sit behind punctuality, competence and a smile. It is not a formal diagnosis, and it cannot establish why someone is distressed. People who appear capable may still experience restless thinking, physical tension, fear of mistakes or difficulty switching off. Physical symptoms should not automatically be attributed to anxiety, particularly when they are new, severe, changing or worrying. As a BABCP-accredited CBT therapist and clinical lead at The Lyceum Clinic, I’m Sanah Younis and I work collaboratively with clients across West London, including Chiswick, Ealing and Richmond, as well as online. An assessment can explore thoughts, behaviours, body responses, health, sleep, work and support in context. If behavioural experiments are considered, their rationale, pace and suitability should be agreed individually rather than followed as a general instruction from a blog. Many people describe anxiety as feeling oddly productive, while also noticing costs such as sleep disruption, missed moments with loved ones or constant tension. These experiences vary. Therapy does not promise a particular outcome, timetable or way of functioning; it can help consider what support and change may be useful. It may help to begin with a practical description rather than a label: what is the person doing to keep up, what becomes harder when they pause, and what is the cost to sleep, relationships, health or enjoyment? These questions do not determine a diagnosis. They can make a first conversation more concrete and help distinguish between a difficult period, a longer pattern and a need for medical, practical or psychological support. Sometimes the pressure comes from inside, such as a belief that rest must be earned or mistakes will expose inadequacy. Sometimes it is rooted in a real environment of high demands, uncertainty or responsibility. Often it is both. Therapy should not assume that a person can simply lower standards or remove external pressures. It can consider what is within reach, which expectations are negotiable, and whether support, adjustments or a medical conversation should form part of the plan. There is no need to wait until work, sleep or relationships have deteriorated completely before seeking help. Equally, asking for help does not mean a person has failed at coping. A first conversation can stay practical and tentative: what has changed, what matters most, and what form of support would feel possible now. If you recognise these patterns in yourself, you don’t have to keep shouldering them alone. Contact The Lyceum Clinic to arrange an initial conversation with me, Sanah Younis, so we can explore whether CBT might help you feel steadier, more present and more able to enjoy the life you’ve worked so hard for.
