In order to get an official diagnosis, your condition has to be limiting or disabling you somehow. It is possible that you are well adjusted, at least as an aspie and therefore had a hard time getting diagnosed or recognized. Personally I am constantly using adapted behavior to survive in neurotypical interactions, so it's been somewhat hard for me to get a diagnosis. I took a few aspie tests that were positive indicators of aspergers, but the adaptions I've formed have the function of a wall for me. I've adapted so well, though still not quite good enough, that most people expect me to be neurotypical and arrive at neurotypical conclusions and understand things the way they do. After taking the aspie tests, I went to a psychiatrist, a social worker, and my regular doc and they responded as follows...
psychiatrist ~ "many tests must be done, I'll test you for everything else first, and get you nice and drugged up in the mean time"
social worker ~ "you are socially stunted because your personality is underdeveloped"
reg. doc. ~ "you are too smart, don't have a problem with eye contact and you talk too much"
The problem here being that I have too much of an interest in medicine and read too much. Since doctors like to have discussions based on the exchange information and I do too, I seem like an introvert to them. They are interesting minds and are full of knowledge and my thirst for info, good discussion, and my inherent trust of doctors for most things is makes them easily approachable, not to mention their bedside manner... we get along, they don't see how terrifying it is to walk up to someone I don't know and get a date or make a friend. That is where I "scream," "reek," and "seeth" aspie from my very core and I can only imagine that the people I've met are saying to themselves "wow I just a met a talking chihuahua!"
On top of self correcting, I was self medicating with nutraceuticals to reduce anxieties and asocial behavior and realizing that so many of them had been been indicated for the treatment of aspergers, I started looking into aspergers...
