Waking up tired for 2 years

18M.. Moved house 2 years ago. At first there were no curtains so I wasn’t sleeping well and the tiredness began. Then i added some to block out light, but the waking up tired continued. I always sleep 9 hrs, not waking up at night. My room is dark and quiet. Good sleep routine, environment, and hygiene. Blood tests, examinations, and sleep study done. No caffeine, drugs or alcohol. Tried CBT, melatonin, magnesium, acupuncture, meditation (not all at the same time). I’ve been away from home for periods up to 2 weeks and sleep has been the same there, never feel refreshed. My diet is good and I exercise regularly, and my mental health is good. I’ve tried everything, doctors don’t know what to do, any ideas greatly appreciated.
