Good for you shell....... (and welcome to the forum!). There are plenty of people that don't talk much in meetings and always a few who do. I'm the kind of person that is mortified to speak in front of people, and after a few times going to AA I found myself talking..... I felt that comfortable. I think it was because so many of their stories and struggles were just like mine!
Just try it..... you really don't have anything to lose and maybe much to gain!
Hope you'll let us know how it goes.
