Good for you for going to a meeting. I also put off going for a very long time. I'm not a people person and not one that enjoys meetings and that type of thing. But I now have a home group that I attend weekly and another group in a nearby city that I go to occasionally. I always come out feelling better than I did when I went in.
There were people in both locations that I could identify with and I made it a point to try and talk to them. You'll be the same way...just give it a little time. And in the meantime we're here!
