I've asked before, but the situation has taking a new turn, I need help from someone who's dealt with this?

I'll be praying. Have faith is most all I can say. I can't quite gather if you're Christian or not but if you're not God always can help and will always be there for you. She may be mad at you now but she's probably just mad at the world in general... Try apologizing or saying you were trying to be kind and caring like she always is for you and her friends. Make sure she knows that you want her here with you. Make sure she knows their are others who love her and don't want her to leave.
