Not sure of this anxiety related or not, sorry if it isn't, but feels like it should be related to anxiety.

I was watching Sisters and one of the characters asked the other why they were so afraid of having fun. Idk why but I felt that. I don't drink, no weed since high school (realized I didn't like it so stopped, just tried a couple of times). I went to a bunch of parties but never enjoyed them, mostly FOMO or a friend wouldn't wanna go if I didn't.

Was/am jealous of ppl who can go out partying/clubbing and enjoy it, or try new stuff and have fun. Always thought I just didn't like those specific things but what if it is a fear of having fun somehow.

Anyone else who can relate somehow?
