I can't figure out if I have Asperger's, PDD-NOS (how do you even diagnose that?!), or Bipolar. I have been diagnosed with Asperger's because of "an inhability to control emotions" and "doesn't talk to anyone but herself", but I seem to have more similarities with Bipolar I or II disorder. For example, I can have these outbursts when I can't do something as well as I think I should (perfectionism---not sure if this is anxiety or just part of my personality), I get extremely depressed. When I don't understand something, I get depressed and inconsolable. When I think I'm hurting other's feelings or offending others, I either start apologizing excessively, or I start self-mutilating and say, "I'm evil! I'm a monster!". Yet there are times where I feel extremely happy or hyper, and I can't stop laughing and I go on a creative fit and start writing everything (then again, I'm what my mom calls, "artsy", and a lot of famous poets such as Emily Dickonson did that, so...). I'm going to get psychologically tested again next year, so if my results change or are inconclusive, bear with me! I'll get the Mystery Diagnosis crew for them to figure me out!
Anyway, contrary to what everyone thinks, people with AS can be more emotional than others, which is why they can't contain themselves or shut down. Or, at least, that's what I think....hope it helps, or my mom will feel the wrath of my guilt!
