Well, SG, my dino-advice is the same I've been dispensing like so much reality-smacking fairy dust all over these fora -
You are you. If you try to be anyone else, you won't fool anyone, and you'll make yourself miserable. If, on the other hand, you adopt "Illegitimi Non Carborundum" as your personal motto, and joke 'em if they can't take a frak, you'll probably find the anxiety dwindling - after all, what is there to be anxious about if you genuinely don't care what people think?
Took me almost forty years, and a ten-year marriage down the tubes, to figure that one out, and that was before I even found out I was Aspie!
Now I've got a beautiful wife, who loves me for who I am, not for who she thinks I am or what she thinks I can do; two wonderful children, one autistic and one (as far as we can tell) NT (he's only 18 months, so it may be too soon for a definitive diagnosis of NT Syndrome); and a great best friend and cohusband, who's currently in Iraq with firm instructions to keep his bloody head down. And none of this would have ever come to me if I'd tried to pretend to be "like everybody else"; I'm not, and they can all tell on first meeting me.
