Hi Amy,
Welcome to healing well. You are so young to be having to go through so much pain. I really do feel bad for you. But you have come to a good place and that is good.
Do you go to any counseling? I think that would really help you. Sometimes it takes a while to get to trust your counselor, but in time it happens and you can get all these things out and in the open and deal with them.
I am sorry that you feel that you can't cope now at your new school. Is there a school counselor that you can talk to? I am sure that your freinds wont think bad of you for what you have been through. This wasn't your fault and you need to know that. You didn't do anything wrong.
On that note I will end here, I hope that coming here will help you. But I strongly recommend counseling. I really think that you would benefit from it.
Keep posting and know we all care about you.
Hugs, Karen
