I get anxiety before inviting them, when i invite them, after i invite them, in the days coming, in the very day hours before we meet, during the moment, etc.

It's all just too stressing, overthinking about everything, if they really want to go, if they're just being nice, if they actually like me, if they're actually having a good time, if they'd rather be doing something else, maybe I'm too stupid for social interactions, maybe I'm meant to be an asocial hermit
