You tried to commit suicide over this? Are they serious? They must not care for you too much if they continue to do this. It's dangerous for everyone. I've never done anything while psychotic, but if I had tiny ones screaming at me, I might whap them. You don't know when you might snap. Kids are tough enough when they are your own. This might sound crazy, but i would not open the door and tell them if they don't go away you'll call the police. These are toxic relatives. Get out and protect yourself now.
