how to fix social anxiety in loud crowds?

just recently I went to a restaurant with some new and old friends, I know I wanted to socialize, ask questions and get to know these people more and catch up on how their life had been but the place was so loud and I sort of just lost my cool and ended up being very inwards with myself, never really being able to talk only listen. I'm completely fine with conversing 1 on 1 it's just big groups that completely throw me off. I also want to add when I don't quite hear what people are saying I sort of replace the mumbles and they end up being negative thoughts from in my head as their voice and I start believing this is what they're saying about me. I don't know how normal of a thing this is to experience so if anyone could offer any advice it would be greatly appreciated!

 

yeah it's like I know they're not but I just really convince myself they are. I did notice once I'm actually joining in on the conversations it eases up it's just hard to keep it going.

So would you say I can fix this? I just need to practise talking with more people I guess
