I have a teenager ( 15 ) who was diagnosed with ADHD a couple of years
ago. He has always had trouble getting assignments done in class
throughout his life. He is extremely intelligent but doesn't care to
use himself to his potential. Now in 10th grade he is becoming more
beligerent and mean to his parents and siblings. He doesn't have a
lot of close friends and prefers to spend his time on the computer
IMing. He has ups and downs in school but lately its been really
down...just doesn't care if he does the work and talks of succeeding
and getting good grades to go on to college have no effect on his
attitude. At times at home ( when he's in a mood ) he yells, swears,
and has become physically destructive ( though minor right now ). Bad
bouts will end up with him in tears and apologizing saying he doesn't
know why he does it. On Straterra but really don't know if it works.
Anyone have problems like this and were you able to solve them?

He really is a good kid, but these episodes are heartbreaking.
