14 year old DS always been a challenge with an explosive temper ( but can hide it at school). He's vile. Violent and aggressive at home, punches and kicks his brother, squares upto me and threatens us. He rules the house. I have to warn anyone who visits.I've had GP referral to CaHMS who couldn't help. Counselling for him, which he played along with. School who dismissed it as teenage angst ( after he's wrenched a door off). I've tried rewards, sanctions,rules, everything. I feel suicidal..and he laughs in my face.
