I go to AA and it is true that meetings are different. There are several at a church near me but each meeting is different. One is a Big book meeting, another is a mini lead/discussion, another is straight discussion and two others vary but are mostly lead meetings. I met several people I click with and the ones I don't I say hi to but I don't hang around then too much.
Maybe instead of a lead meeting you should try a discussion meeting. They usually bring a topic to the table and then people take turns discussing it. You don't have to add in or comment if you don't want to. Sometimes I get more from just listening.
