This is relatable, mine is somewhat similar. It feels like a very specific version of performance anxiety that unfortunately affects the most banal social interactions. It is obviously multiplied tenfold when I'm in a situation where there are actual stakes (an interview, a first date, etc), but it still applies if I am just talking to a friend of a friend at a party that I don't know very well. The stakes feel very high to me because it's our first time talking.

It's less that I need them to like me or fear being disliked and more that I am just way too conscious of the stakes and the social interaction that's happening, which causes my brain to sort of freeze up. It feels like when I used to play tennis in high school. I'd do great at practice, then freeze up and barely remember how to hit the ball in games because the stakes on each point felt so high.

If I'm around some good friends it completely goes away. If I have hung around the person enough (even without directly talking to them), it goes away. I've also had random days where I don't feel the performance anxiety and performed really well in those situations (and coincidentally some of those days I'd meet a new group of friends or a girlfriend). It's extremely frustrating. Xanax makes the performance anxiety go away completely but slows me down cognitively so I become much less witty and interesting to talk to.
