Nc for this as my other posts would out me. AIBU to ask for your help?
I have 4 DC,two who live at home. DS2 (youngest,6) has always been a hard to deal with child. He could never even sit still. He would throw himself off of chairs onto the floor, run into walls, just generally do dumb things and felt no pain. He still does this now. He is often violent towards DS1 (9) and sometimes myself, DD2 (18) and my DM. When I try to discipline him, he growls and throws a tantrum. His mood is like a light switch. He's often very lovely and cuddly when he wakes up, but will snap instantly and become violent and nasty. This happens all day long. He says he wants everyone to die, he hates us, doesn't want to be here anymore, etc. I feel as if I can't do anything to stop him. School say he's a model student. But at home he is a nightmare. He drew a picture of me being stabbed in the back with a knife today. I don't know what to do anymore.
DD2 was recently diagnosed with Borderline Personality Disorder, and I have Depression. Myself and his father spilt 3 years ago, but this started before that.
