Here are a few first person accounts of having ASD

Jean Birch was 43 before she found out she had Asperger Syndrome. By learning what made her different, she was then able to accommodate aspects of her life instead of trying to force herself to fit in.
    Here Birch talks about what it might have been like if she found out earlier in her life:

    If I had received the diagnosis early in life, and had been told what this entailed, at least I would have been forewarned about possible dangers. I would then, at least, have known that dating, flatting and other social situations would be risk areas for me, and I could have chosen to do things differently.  Also, I would have had access to support persons who understood my differences and who would have kept an eye on me to some extent. I could have asked such support persons for advice and guidelines. I would have had the necessary data on which to base important life decisions. For instance, I now understand why I had less interest (than my peers) in dolls, and, later, babies; my brain was wired up differently. (I do not wish to imply that all females with Asperger Syndrome are exactly like me, however, as this is not so; some do marry and have babies.) For me, though, realising why I was different would have meant that I could at least have chosen not to get married. Also, the information would have helped in choosing suitable jobs, and avoiding unsuitable ones: jobs which involve multi-tasking, frequent sudden changes in routine a lot of pressure and anxiety, or having to think quickly on the spot, are not (as a general rule)suitable for persons with Asperger Syndrome. For example, my job in a cafeteria meant multi-tasking on a grand scale, which caused too much stress, and was therefore unsuitable. A person deserves, at least, to have the data which to make a decision. As things worked out, I did not have this essential information (the diagnosis of Asperger Syndrome) at the time of getting married; therefore, I do not blame myself for making the wrong decision. Having made the wrong one, I think that our mutual decision to split up was the right one. It gave both of us a fresh start, and Lindsay [my ex-husband] is now remarried, with children.
