Speaking as a shy person myself, I'd say give it some time. You don't have to get to know everyone at once. Yes there is a social/fellowship aspect to AA, but it's the program that is the basis and I think I would've been better off if I'd spent more of my early time in AA listening and learning rather than wondering what I should be doing or where I fit in.
People in AA are also at various stages of recovery themselves and are 'works in progress', they're finding their own way. At nearly 3 years in, I'm still learning, it never really stops. I felt very intimidated by some long timers in the beginning, but we're as human as the newcomer
