I could make a nice, long list (I'm pretty touchy) but here are a few of the worst:
Gaslighting/being invalidated: being told what I really feel/experience (contrary to my own statements), or having my behaviors/preferences retconned, by somebody who can't possibly know because they aren't me.
My appearance/having my picture taken. I don't share photos (or do video or voice chat) basically ever.
"Everyone is beautiful", "you don't need a relationship to be happy", and other glib, projective nonsense.
For forty-seven years I've put up with it now. I must stop Christmas from coming ... but how?
I think I'm very sensitive about how other people feel when I am talking to them. I feel the need to keep them in their best mood..sometimes I even feel as though their feelings matter more than mine. Exhausting.
My appearance. Either when I don't reach my own standards or other people making negative comments. I've noticed a lot of times people make comments about your appearance, not from concern (because they may barely know you) but just to make conversation, which makes them a rude, uncreative and lazy conversationalist.
I used to be sensitive about people making comments about me being quiet / shy, but that rarely happens anymore for some reason. At least not to my face in this culture. And I've noticed as the comments on that petered out, so did my care for them. I don't think being quiet and shy is as overtly stigmatised in adulthood where I am right now. If the comments started increasing I'd be bothered again I guess.
I don't like people making comments about me looking anxious.
I also don't like people making jokes at my expense / teasing me in an unfair or mean way. I had a friend who used to do that and I basically dumped her because of that (and another super fcked up betrayal thing she did but that's not relevant here, because I don't think I was being sensitive about it, I was just reacting like a normal person would).
