I seem to return to this site only when things get really difficult. I apologize if this seems selfish to anyone. Sometimes life gets in the way of my good intentions and I'm sure you can all understand how busy a difficult child can keep us. My son was on the highest dosage of Concerta they'd allow for up to a 17 year old. It wasn't enough, but it was working. They added Prozac, said he had a mood disorder and reduced the Concerta about a month ago so they can try him on something else. His psychiatrist is only in town once a month, so we go back on Friday. I'm terrified they're going to reduce the Concerta again. He's gradually become more and more aggressive, hateful and abusive. His manipulative behaviours have my brain working overtime and my ten year old daughter is in constant fear because she's become the punching bag for his anger. I've obviously stated and enforced to him that physical violence will not be tolerated. I've explained that I love him, but that anyone abusing one of my children will not be excused, not even him. He is thirteen, not normally aggressive at all and he's so full of anger. I'm fed up with him one minute and worried sick about him the next. Yet, I have to protect my daughter too. Oh, she's no angel, but hitting isn't acceptable for any reason and he knows this. He's not just slapping, but leaving marks and welts, even bruises on her. I can't condone this type of behaviour. ADHD is one thing, but things are way out of control. I still think he has early onset bipolar. So far, every medication change has resulted in this type of chaos. Does anyone have any suggestions on how I can handle this until his medications are changed?
