Wow, I'd be really bothered by the comment regarding makeup and new clothes. If people won't like you because of that, then they're pretty shallow. And I'm sorry for all the teasing and bullying--that's awful. It sounds like your T doesn't really get it. Would you consider possibly trying a different T?

I'm also someone who doesn't really buy into the positive affirmation thing. I know it works for some people, it's just not something that would work for me. It's sort of like trying to keep a gratitude journal. It's something my T has suggested a couple times because it's been shown to help people. And I've tried it briefly a couple times, but then I end up feeling guilty because if I have these things to be grateful for, then I shouldn't be feeling so bad.

Out of curiosity, you mention your body feeling stiff--have you tried something like physical therapy for that? You could have, for example, high muscle tone/hypertonia, that can cause muscles to be stiff and tight (my daughter had the opposite, low muscle tone, and got some OT/PT for it).
