I can only imagine what he has been going through. Young kids are not politically correct.
Someone very close to me went through something very similar with prosac. Before it was all over they had her prosac stacked with tegretol and were going to start lithium. Luckily she walked away from this and is more stable than me now.
Unfortunately, my son has also been diagnosed with Asperger's Syndrome. He's never had good social skills and always has somewhat of a rough time. But this happened at the very end of the last school year, and he didn't go back until Fall. The teacher hustled him out of the room and spoke to the kids. It really hasn't been an issue for them.
My son feels embarrassed and humiliated, and he is convinced that they all think he's crazy. But this isn't something they bother him about. The things we deal with seem more rountine than that. (Today was someone spilling a bottle of white-out in his backpack, ruining it and a library book.)
