Nervous about meeting bfs family & friends

I'm 20f, he's 21m. We've been dating for 6 months. I have briefly met his mom and sister, but I was really awkward and didn't say much and left after like 3 minutes. Tomorrow I'll see them again and also meet his dad. I'm introverted and I think his whole family is too so that's part of why I'm feeling anxious. If I don't lead the conversation, there won't be a conversation. My bf's ex (they dated for 2 years) was outgoing and fun and I think that made my bf's family feel relaxed. I keep comparing myself to her. I am dreadfully awkward and can barely keep a conversation or form an articulate sentence.

I'll also meet a few of his friends tomorrow. I've never met them and I'm scared. I am not really that funny of a person and I know people use jokes to help break the ice but I can't be funny when I'm anxious. I'm not used to being around groups of friends, i usually just hang out with people one on one. I know his friends mean a lot to him so I want them to like me
