I understand the fear of the wrong diagnosis. I have the same fear... I do have a lot of AS traits, but I'm sure plenty of them could be explained by something else. I am only seeking an AS diagnosis because I fell apart COMPLETELY upon living on my own in college, and I feel like I need help, and AS seems like the logical place to start because it certainly fits me better than anything else, as far as I can tell. I have major black and white thinking issues, obsessions, and I've never had a very successful social life, although I have had any maintained friends at various points in my life, and relationships, too. Luckily, I'm going to a real expert who is taking several sessions to diagnose me, which will give me confidence in any diagnosis I receive. I feel like there is a good chance she will diagnose me with AS, a good chance she will diagnose me with PDD-NOS, and a good chance she will just say that I have anxiety and while it's clear that I have many AS traits, my symptoms don't match the DSM-IV close enough to warrant a diagnosis (she has noted that my social difficulties do not seem bad enough, but I don't know).
