I have been to a councillor before at my high school about symptoms of anxiety and she told my mum that I may have symptoms of an autism disorder. I don't really know what to look for symptom-wise but i've done a little research and so far this is what I experience (almost daily) being easily irritated, I don't like doing things spontaneously - I need to plan it out beforehand, I much prefer to work alone than in groups, I fidget a lot, i've always been overly emotional, being extremely sensitive to criticism, daydreaming/zoning out especially in school, and excessive talking. Sorry about the long list.
