I had never heard of it until a few years ago when a friend of the kid's who has it mentioned it to me. He basically told me I had it. I thought he was talking about skiining or being from Aspen and I misheard him. He explained it, I researched it, we talked some over weeks and months, and I went to a therapist. I mainly went out of curiosity because there is really nothing to do for it, and I've learned to get along just fine really by now. I'm in my late 40's now, obviously younger then.
For me, it was more of a "Huh, well that explains a lot!" thing. I had always thought it was just me, and made myself learn to deal with some things, but there are degrees of how effected you are with it. There is no telling what my prognosis would have been if I had been diagnosed when I was a child. I'm glad I wasn't then, because my Mother was very overprotective and she would have used that not only to gain attention and sympathy for herself, but also to keep me home and where she could see me, and it would have added fuel to her "Oh Frances, you can't do that!" fire. My Mothers psychological pathology is off the charts, really.
I came here to talk to other people who are like me about certain things, and who understand things that others, my husband and family included, just shake their heads and roll their eyes about.
It really depends on what you want a diagnosis for. To explain things to yourself, if a diagnosis will help you in work or school, etc.
