I have severe insomnia, OCD and ADHD. That “holy trinity” is an absolute nightmare for me. Ever since I was an infant I either go several days without sleeping or several weeks averaging 4hrs of sleep a night. For perspective, I’m a 110lbs female and would drink a bottle and a half of Z-Quill and still lay down with my brain being wide awake. Over the counter sleep aids, cbd, thc and melatonin didn’t do anything for me. Only remedy was Trazodone. Had a financial/insurance issue disallowing me from affording more Trazodone. Was awake for 6 hellish days after a couple years of decent sleep. I know, atleast from your daughters perspective how hard it truly is to fall asleep for some people. And I cannot imagine how hard it is as parents. Bring her to a psychiatrist, saved my sanity.
