Some meetings are just like that.
Ask yourself what YOU bring to the meeting? It isn't all about what you can get out of it. Do you have a home group? As McRibb suggested, some service work (making coffee, helping to set up or clean up, acting as your group's Intergroup rep or literature rep--all of which you don't need a lot of sobriety to take on) can help get you more involved.
Get a couple of other guys who want to explore other meetings. I know a few people who made it an adventure--a road trip.
Negative people at meetings can teach you tolerance, and also illustrate how much better it is to share the solution at meetings than to vent your problems (which is better done with a sponsor). Speaking of which, do you have a sponsor yet?
