What Do I Do If I Can't Tell Or Trust Anyone? (Long Whiny Story)

This has ALOT of personal information but that’s why I’m anonymous!... No judging either. I need serious advice !

I’m so paranoid I can’t sleep when it’s dark. Even with the light on. If it’s dark outside, I wont sleep. I’m just sooo scared and paranoid about things. I think the only time I can feel safe to sleep is 1pm – 3pm.. that’s my sleeping habbits. Plus I’ve never been able to go to sleep on my own. The docs are thinking of putting me on meltonaine or something… and to help sleep I have to have a pacifer. I’m a teenaged girl, I’m way too old for a pacifer! It’s too hard to give up too. I’ve tried sleeping without it! It’s impossble…
I don’t go to school anymore because of all my mental health problems (my ASD, OCD, ADHD, Tourettes…) I had severe depression this time last year but I’ve been put in hospital for like 9 months and on a medication called Ripserdone… I don’t want to tell my doctors how paranoid I am about going to sleep at nighttime! I’ll probably get detained under the mental health act again and put in hospital which is 3 hours away from my family and home !:(

I don’t know what to do about anything! I’m so confused!
Please help :(

Thanks.
