Hello, and welcome and congratulations on your decision to stop drinking.
Going to a meeting is a great idea, you'll meet people there who are there for the same reason as you, so there is nothing to fear.
Maybe introduce yourself as a newcomer, or, you don't have to say anything if you choose.
I was so scared when I went to my first meeting. I actualy walked by the place several times before I went it. Best decision I ever made.
I hope it goes well. And keep posting here whenever you need to. I'd love to know how your meeting goes.
Best to you.
