What everyone has said.
And- most of us felt like you did the first time we considered going to a mtg. I went to the back and sat and didn't enjoy being there but kept my mouth shut and tried to listen. That was way before I actually quit - then when I finally did, I went, sat in the back and listened as best as I could through my rough detox phase. And I kept going. It has gotten much better and I don't like it every time but I go; you really can get to the point it is very big blessing in your life.
I would venture it is worth trying. Good luck!
