Why am I awake all the time

I am ALWAYS awake for some reason and I can never sleep at night. Since I was like 8 I’ve never been able to sleep at night. I used to get really bad night terrors and I think I may have a little bit of schizophrenia or something like that because i hallucinate sometimes. Other times i would wake up to this AWFUL quiet that was so quiet it was almost painful and then all of the sudden everything would get super loud and even quiet things like the air conditioner turning on would make me fall on the floor and scream in pain. I also used to hallucinate ghosts and monsters watching and/or attacking me. Nowadays I dont hallucinate nearly as often but I do get very paranoid at night. For some reason no matter what I do I can never sleep at a reasonable time without taking sleeping meds. Its not super inconvenient but if just ONE night I forget and its past like 11:30, i cant take the meds otherwise I’ll sleep in too late (I get really bad anxiety if I wake up past 11 am). Its really weird because i can be on a proper schedule using sleeping meds for months but if I miss taking them one single night i cant sleep at all. There will be times where i only sleep a few hours over a span of a week or so. This was especially bad in school, middle school and my sophomore year of high school specifically. 

One weird thing is that for some reason whenever I watch moist critikal play metal gear rising I get really tired and can sleep most times?? Idk if this is something I’ve conditioned myself to because I usually play moist when sleeping because I cant sleep without noise but its only that video. 

Anyway idk why im yapping, probs because Im awake now after missing taking my meds. Luv u guys thx <3
