Rosie, dear, it's a very sad story.
You are a VERY courageous and strong person to go through this and be able to go further and be sane and try to deal with it.
You know, I also had a rough adolescent years and when I remember about them I tell myself how strong and wonderful I am to go through all this and still become a person I am now.
I just have one question where were your parents all that time? When you were trying to fall asleep for 4 hours every night where have they been?
Havent' you had playdates with other kids?
