I can *absolutely* relate to the meeting-fear. I have social anxiety and often feel so confident on my way to a meeting, then I get to the door and I'm terrified, sweating and want to vomit. That being said, I often sit in the back and there hasn't been one time I've ever regretted going to a meeting.
You don't have to talk to people. If you go in and want to connect, then go and make a coffee and talk to the person next to you. If you are scared, then sit at the back and it'll be okay. Everyone is there for the same reason and no one is going to ask you why you're nervous. It's AA, dude, everyone has had their first few meetings.
