"You mainly suffer from anxiety."— what you've probably been told
POTS / dysautonomia
POTS is increasingly recognised, particularly post-COVID. NG188 covers autonomic symptoms in the post-COVID context; broader Royal College of Physicians guidance also exists. The letter cites the relevant authority for your situation.
The wait: Patients see an average of 7 doctors before diagnosis.

POTS is often missed because the standing test isn't performed. A 10-minute active stand or NASA Lean Test is straightforward and inexpensive but rarely offered without prompting.
- An active stand test or referral for tilt-table testing
- Referral to cardiology, autonomic services, or post-COVID clinic
- Consideration of POTS in the differential diagnosis
How is POTS diagnosed?
Sustained heart-rate increase of ≥30 bpm (≥40 in adolescents) within 10 minutes of standing, in the absence of orthostatic hypotension, with chronic symptoms. The letter requests the relevant test.
What's usually said in the room
