24F I don’t know what girls my age talk about. I’m going to a dinner party soon and I’m so out of practice socially. Help?

So this is gonna sound a little weird but this will be the first time in years that I will hang out with people around my age without my mom (we’re really close so it’s not *that* weird but…still kinda is)

I need to break away from that. I’ve had very little social exposure in general throughout my life. I went straight from being homeschooled to working at home. So because of this I’m kind of afraid to hang out with people my own age because I simply don’t know how to talk to them or how they will act differently when it’s JUST young people (early twenties) and no parents or if they will act differently at all…which probably sounds dumb but hear me out…I don’t like talking about relationships or boys (zero experience whatsoever), careers (cause don’t know what I’m doing with my life & it’s embarrassing), I don’t do any kind of drug, I don’t really curse or and just have very little LIFE experience in general so I’m also afraid of being perceived as boring/childish. But at the same time me going to this thing is an attempt to change that, we all gotta start somewhere, right? It’s just I feel mentally still like a child in a 24 year old body and I’m afraid of “being exposed for it” I’m so behind…but I don’t wanna lie either…like I’m just so afraid that some kind of subject is gonna come up that’s gonna make me sound immature. Alcohol of course can help, but I don’t wanna rely on it, for obvious reasons.

I’ve been particularly insecure lately which doesn’t help (going to therapy btw, so no need to suggest that lol) but I get a judgmental vibe from *some* of the girls going but that could just be ME being judgmental so I’m not going to ditch the whole thing because of a judgement.
