How to handle a child with very bad behavior?

I have a brother who is just like that. He is an angel at school and when he's a guest at houses but the moment he gets home he explodes. Don't feel you are alone. I know how you feel. He will take his anger out physically on everyone and go from 0-60 in one second it is very frustating. We have found out that he is severially A.D.D. and has mental prcessing disorders. This can cause them to do all this for attention and not care how they get it. Most add kida are very intelligent and it sounds like your child is very smart. I would recomend going to a phycoligist or phyciatrist (i dont rememebr which one does what) which ever one tests for a.d.d and mental disorders o would go to. The first step his getting his IQ tested and then they will go from there. There is medison for things like this. He could have an explosive disorder also. I live with someone like your son every day dont kill yourself or go to measures like that. It will eventually get better. I would also recomend seeing a councler or brainstorming ideas with a friend. My brother will shuve cuss throw things and all of the things your son does at my mom it is very sad and will get me in tears. My mom has tried every didpline out there like you talking it out, , grounding but nothing works. He will do what ever to get attention he doesn't casre if he gets in trouble. This sounds like an emotional or attention disorder to me. he will threaten the same things ur son does but please dont feel like your alone. Take my sugestions and run with them.
