Very sorry for you after reading your story. Abuse by any person is a crime, your abusers should be punished however, the services take care of themselves unless you can prove the event.
No it's not your fault, you have quite a few issues to cope with and should not be dealing with it on your own.
Can you seek help from GP, who may offer you counciling and mabey
Meds to help with the stressful situation you are in.
Im unable to offer any help dealing with the law, but please go to GP and get some help now.
Keep talking to us on this site it will be a release valve for you.
Yes having a mental illness does give us a label, disgusting isn't it.
I don't feel I've given you very much help and I'm sorry for that, perhaps somebody else on this site can offer better advice.
Let me/us know how you get on please.
Best of luck to you. xx
