He always hangs out with them at a local place once a week, and I've only gone with him once or twice. That was last year though, and he's been hanging out with a lot of people I've never met. Personally, I would rather stay at home. I'm very introverted and awkward when talking with people that I don't know well. But last week I asked if he would be alright with me coming with him. It's really the only time we spend apart, so I wanted to make sure it was okay instead of just inviting myself. 

He was really happy that I asked and said his friends are always asking about me, so that was really encouraging. But now I have so much anxiety about it. I'm worried that they won't like me, that I'll say something dumb, or I'll be suddenly left alone with his friends and won't know what to say lol. It's making me want to stay home, but we never really go out together so that would be nice, and I really want to meet his friends. 

Just wondering if anyone has gone through something similar and looking for support. I know my thoughts are irrational but I haven't been this anxious about something in a while.
