First Time at GA

[Guest]

I need help in overcoming my gambling addiction/compulsion.I need to do this for myself and for my family. I intend to go along to a GA meeting next week but do not know what to expect. I am by nature very quiet and the thought of speaking out to a crowd fills me with dread. (Shame I don't feel the same dread when wasting cash at the bookies I suppose) Can anyone tell me how the meetings wor, how they are run and what expectations there are of me.
Thanks,
James
