This is a good start coming to this site and discussing your thoughts and feelings. You must have some control at times because someone wants help and is willing to ask for it. You will need a good therapist, someone who specialized in trauma work. Something that has helped me with the angry ones is to ask them what they want or what they are trying to tell me. Most times I will get some response. Sometimes just by asking my anger will diminish. But definitely talk to someone. It does help.
