I think my brother is a psychopath, would it be okay to let you know?
I hope you are kidding. Why do you think he's a psychopath?
Because of all the stuff he did to me.
I'm sorry your brother is caused you such suffering. You should consult a family therapist about the situation.
No one can force him to do anything. He doesn't want to be helped, yet he continues to cause all these issues.
Well, you have to be sure and get him a diagnosis. I know this won't be easy because he probably thinks he is fine. If he refuses to go, just go without him. You don't need to deal with this alone.
