Have a question on legal issues?

I’m 16 and live with my mom and her boyfriend. I don’t want to live there anymore, I am being emotionally abused but no one believes me. I can’t do anything about it, I’ve tried everything to remove myself from everyone and everything…..everything…. there is nothing to do. I want to go live with anyone else but my mom won’t sign the papers to let me live anywhere else I have a record (sort-of) and want to go to foster care. or a group home. but I don’t know if I can go for “no reason”.
