Researching Asperger's has been like reading my life story and having it make sense for the first time. I'm not sure if I can see spending the time and money on a formal diagnosis. I talked to a psychiatrist who specializes in Autism spectrum a few weeks ago because I was thinking about being tested, and she said that while there is a diagnostic test, based on the three or four minutes we were on the phone, she could probably diagnose me based on a "diagnostic interview". I don't know what if any advantages there would be to being formally diagnose.
