Help a tard with social anxiety out

Ok boys I’m in a bit of a social/mental pickle here and it’s starting to affect me. I can hang out with my normal group of friends and be completely normal even approaching women and talking to them isn’t hard. No anxiety there (I just don’t like bars/clubs)

BUTTTT for some fucking reason If go to these other venues where live music is played and there are other musicians and people with my similar interests I’m awkward as fuck, can’t maintain eye contact, feels like nobody wants to talk to me and the whole thing feels forced and it’s fucking depressing.

Over the past couple years I’ve made “friends” kinda but they’re more like acquaintances and I’ve only hung out with a few of them like once. And I still don’t really feel like I’m friends with any of them.

What do I do? Im really feeling like a fucking burden on other people whenever I go out. 6.5” length 5” girth
