I Haven't Slept In Months It Feels Like. I Maybe

I haven't slept in months it feels like. I maybe get one night of good sleep a week.. I've tired absolutely everything, I don't want to go to a psychiatrist because they just try to get you on antidepressants. What should I do? What can I ask my pcp for? I need something very strong, I'm a very light sleeper, but can very get comfortable or stop thinking, my brain just won't shut off at night time. Any suggestions?
