Wow...I'm so jealous of the person who doesn't worry much. For me, the worst part of being not-NT is the constant anxiety. I'm constantly losing things, forgetting things, missing appointments (well, not so much any more), misreading test questions, misreading my calendar, etc., despite my best efforts to guard against such mistakes. Not to mention general awkwardness like walking into things, getting in people's way while walking around, saying awkward things or not making the right facial expression, etc. (Yes, I'm blessed with the ability to notice when I've done something wrong but not the ability to avoid being awkward in the first place). So I'm constantly anxious that I'll do one of these stupid things, and then after I've done them, I feel so embarrassed it's physically painful. Kind of like Miss Nessa, I used to obsess over embarrassing things I did for days, weeks, months, until it got less painful...not recommended. (I do still obsess sometimes, but not for as long).
Cognitive behavioral therapy really does work (although it took a while for me. I used to just argue with myself when I tried to use it, lol). Distracting myself with some sort of fun online activity works in the short term, and I do that more than I'd like to admit.
I wouldn't recommend it, though, for the obvious reasons.
