Just b/c your son probably has ADD/ADHD does not rule him out of life's runnings. Do you realize how minor ADHD is compared to what he could have wrong with him. ADHD didn't keep me from being a nurse, I just needed to be on a small amount of medication. It sounds like if he's getting in trouble in school (one of primary dx symptoms) he'd be better off w/ a little Rx. It may be devastating to you & for that much, I feel you really need to read up on ADHD before you sign your sons' life away. I may not be the sanest person on the planet, but my ADHD pales next to the SI,depression and eating disorders! Step back and try to get things into perspective here. It is good is your son is ADHD, that he is getting help that he needs NOW! It can turn into juvenile rebellion as he gets older w/o the help he needs.
Sit down and voice your concerns w/ the people at his school. Speak now or your son could go in the wrong direction later on....
