Dating Apps are SCARY

No fr how do y'all meet up with people without wanting to like throw up LOL. I'm talking to this girl on an app and she said she wants to meet up but I feel like such a pit of anxiety in my chest IDK T_T 22 and never seriously dated anyone, I feel like a lost cause. Like deadass idk who I am as a person or what I'm even looking for- I guess I should figure that sort of stuff out before dating but like cmon man IM 22! Basically 23 at this point so like what gives. 

I guess I just have to like say yolo and get past all my intimacy anxieties , but it's just so hard. Idk how people date and meet people so easily irl it feels like this wall is preventing me from doing anything. Like I went out the other night with an old friend of mine and met all of their friends, but I literally just stood there frozen most of the night because I didn't know what to say. I felt so uncomfortable it was frustrating. I guess the more I do it the better I'll feel about socializing.. so. I can only hope :') Why is it so difficult for me but not other people it stinks.
