You've just described my DS7! And I would not necessarily take that as an indication that it's not something to discuss with the doctor, either. I'm not sure to what extent, if any, the mood swings or extreme moods have anything to do with DS7's diagnosis of Asperger's. His is almost exclusively a social thing, but that could still include the mood things as far as my thinking goes.

I'd like to say I hope that helps, but I can't see any way in which it conceivably could, so....
