I wish I had real-life contact with other Aspies. That way I could have a knowledge base from which to gauge my own degree of "aspieness".
AS affects every aspect of my life. Still, I don't call it "severe"... because it really is just a different way of thinking. A lot of my AS traits--stimming, introvertedness, hyperlexia--are neutral traits, not disabilities. And my special interests and creative, "out of the box" way of thinking are assets that most NTs don't have. I take an intense joy in the acquisition of new facts that I haven't seen in anyone but one of my professors--and he's an eccentric physics prof who, if he isn't an Aspie, is pretty close to the spectrum.
But then... I have very few friends--right now, I have only one, not counting housemates (and she used to be a housemate). I've never had (or wanted) a date. I was bullied as a child because of my insistence on truth in the presence of lies from my stepfathers. My special interests have taken over my life so completely that I failed in class, became depressed, and ended up in the hospital. My sleep cycle is unpredictable. I can't focus on anything unless I hyperfocus, and that usually only happens with intensely interesting things. I have sensory problems that force me to avoid crowds, noise, strong smells, and anything but cotton clothing. I have a hard time holding a job that isn't absolutely fascinating.
My AS causes problems for me. But it also solves problems. I am not vulnerable to many problems that NTs have: I will never become a gossip, a liar, a drug addict, or a con artist. I will never shun learning. I will never let the lure of popularity shake my loyalty to friends. My moral code is consistent and I can be trusted to follow it. I may have meltdowns, but they're temporary; I will never be permanently emotion-driven. I'm not prone to prejudice; I don't blindly follow leaders or factions; I'm not swayed by emotional arguments or catchy slogans.
I don't know how to categorize my own AS. I wasn't diagnosed until I was 22 years old--surely I must have been compensating somehow for all those years! But then... all these problems now, in my first unrestricted environment... AS gets better as time goes on; but it's causing a lot more problems for me now than it did when I was a child (barring the bullying, which I'm glad to be rid of).
I think that "severity" might be the wrong word to describe Asperger's traits... the "strength" of the Aspie traits seems a better way to put it.
My AS doesn't mean that I have added "symptoms" of Asperger Syndrome in my otherwise normal life, and that the more severe they are, the worse the disorder. Rather, it means I've traded some benefits and drawbacks of an NT brain for the benefits and drawbacks of an Aspie brain.
I like the trade. I'm willing to struggle in school and at work if it means I can take such joy in learning, and learn so much about the things that interest me, and be so unaffected by the problems that plague NTs. It's worth it.
