I don't know if it's imposter syndrome but when people show they like me when they've not long met me (invite me to stuff, compliment something I've done, tell me something about me is great) it makes me feel weird. Like, why do you want me to come? What's so great about that thing I said or did?
I usually really like the people too and am chuffed they want to invite me to stuff. It's just it makes me feel weird and really self conscious. Is it just me or do others feel the same?
