First, I should share i've never been actually diagnosed. But, it's very probable. My nephew has been diagnosed. He names it, even though he knows the name for it, but he calls himself Dark Nore (maybe Dark North, but it sounds like Nore).
I, as a child, just thought nobody liked me. I didn't care why. I just thought it was wrong. My best friend was actually my stuffed dog, Fluffy. I still sleep with her at night or I get nightmares. I did have a best friend human growing up, but she didn't understand me. Nobody did but Fluffy.
When I got older, I decided I had to have been adopted. But, all the papers explaining my birth seemed legitimate, and I have so many physical qualities of my father that they had to be my parents. So my mom being abducted by aliens theory was squashed.
I spent many years not thinking anything was wrong with me, but the world around me. My mom kept swearing something was wrong with me because of the temper tantrums being so hard core, but I kept swearing something was wrong with my sister for causing me all that anger. In the end, we were both right.
Then I spent years saying I was strange or weird, not because I thought so, but because that's what people would tell me out of love. I always thought it was related to my high IQ. I figure I was book smart, so I was lacking on the common sense and social skills like many geniuses had in the past.
When my nephew showed some strange signs that my friend thought was autism, I still didn't know about Aspergers or PDD-NS. I knew whatever he had was also what I had because we were too similar. That's when I decided I must have something wrong with me. I never gave it a name, but I just referred to it as whatever it is my nephew and I have.
When he was diagnosed Aspergers, I still thought it was wrong. I researched and researched to find out I was, for once in my life, wrong. Actually, not so much because we'd be PDD-NS because we both had a speech delay. So hah!
Actually, I came to this forum to learn more about my nephew, and it's therapeutic to see other people have the same or similar experiences as myself.
