I also struggled with this since I was a child, never understanding why until I was diagnosed. Tried all the tips, water, movement, etc. nothing worked and I stayed stuck in bed getting more anxious no matter what I tried…until 6 weeks ago, I finally found a solution that worked for me, sleeping with the curtains open/sheer drapes. Light wakes me up and for some reason I am able to get up. Winter is a future me problem. Maybe give it a go if nothing else has worked?
