Yeah, I was diagnosed with it by two doctors while in my early 20s (having seen them for completely unrelated conditions).
I was something of an outcast as a child. I was quite intelligent, with a large vocab even when very young, and exceptional with numbers. I constructed all sorts of elaborate games which I played by myself, writing detailed rules and keeping statistics for everything (some of which I still have today). I also had a habit of constructing elaborate and outrageous fantasies about myself.
Most of my time was spent with adults than children; I realise now that was because adults can carry a conversation, often by asking direct questions, which was the main way I could communicate apart from one-sided ramblings about my interests or fantasies.
As I got older, I became obsessed with numbers. To this day, I spent several hours a week on statistics. I was completely unable to relate to my peers, and my only conversations came with either adults or in writing online.
I really struggle with eye contact. When I was younger, I didn't do enough. Until recently, I did it far too much until a couple of people told me it was really disconcerting. I'm still really conscious of it today.
My interests are quite eclectic and often very specific portions of a subject - for instance, I have no interest in medicine overall, but am fascinated by certain viruses and bacteria. I barely watch football, but love the stats.
I also talk to myself a lot, and, as a 27-year-old solicitor, have been known to play with balloons and jump to touch the ceiling in my office. At parties, I stand in a corner by myself and feel awful.
I have a dreadful habit of confessing really personal things to people I barely know; indeed, going out of my way to bring it up in conversation. My illness (bulimia), relationship problems, etc - all divulged to work colleagues who are virtual strangers. Maybe I like the attention, or just having something to say. I don't know.
