I hate to say this, but you need to write your brother off. He had damaged you physically and emotionally and if you feel you have to be worried about him being around your daughter, then she shouldn't be around him! He is not your problem. Your mother is not your problem. I wish her well with her addiction recovery, and hope she remains strong, but only she can make her own decisions. You need to take care of yourself and you daugter. Everyone has enough stress/hardships to get though with their own lives...you DO NOT need to be worries about someone else's.
