Based on your description I think some form of autism is possible. I don't think you are talking nonsense.

I think that CosmicRose's post was very dismissive. I never would have brought up the possibility without doing tests online and tons of research myself. Also, females can exhibit Asperger's differently than males.

I know several people who are self diagnosed, mostly because they lack the ability to have an assessment due to it's high cost, or unable to find someone who will deal with adults. As you know, a random psychiatrist isn't going to be too helpful with this. I don't think it's a matter of self diagnosis being real for Asperger's, but it is possible it's not accurate. It's hard to be objective about yourself. When I was considering the possibility that I had Asperger's the people who I talked to online said that unless I needed it for some reason, such as accommodations at school/work, that it might not be worth doing. For me though, the fact that I might be wrong made me decide to be officially assessed.
