Depression from family

My brother wants to throw me out of the house my dad lives in;as do i.to supposedly take care of him. Which theirs no one to watch him at all. He wants me in a halfway house cause I have PTSD/DID. Or multiple personality. I got this from my family growing up, and no one caring what happened to me. I'm scared I won't get my pills I need, or have them stolen. I'm not getting any help from law. Cause I am told he has no idea of what he's doing. Even if I'm groped. No one is caring about what happens to me. At all saying I'm lying.
