My eleven year old is ADHD and who knows what else. He takes Focalin. His dad and I are divorced. When he returns home after visiting his dad he is out of control. The ex does not give him his medications. He got home at less than three hours ago and I've been punched in the back numerous times, had a bean bag thrown at me, had Dr. Pepper spit and thrown on me, been bitten. Help me please. I'm at the end of my rope. I love my son but he's killing me.
