Well, im sorry you are so bitter, I was to for a very long time. I do understand, I remember gettin the snot kicked out of me by so called, staff members. I remember having to lie and make up stories, just to get to the next phase, but as I stated before, I made some good friends.
Did you have any experiences that were positive? Did you not make any friends?
As for acting like a child, sometimes it is nice to step away from the norm, and reconnect with old friends, and just let your hair down.
I have ajusted quite well, I am actually a fairly successful adult.
