Can you check out a different meeting? I'm not sure how large of an area you live in, but hopefully you have some different meeting times and locations to choose from. I've noticed in my town that different groups are REALLY DIFFERENT! LOL I might feel incredibly comfortable at one and totally out of place and awkward at another.
I'd say if you feel bad when you leave, try to find another group. Does your area have recovery groups other than AA? That face-to-face support can be OH SO HELPFUL sometimes. It can't hurt to explore all your options. But I say definitely don't continue if it's making you feel bad.
That's defeating the purpose.
