I've had similar experiences to you Stevie. I've found that finding meetings where people get called on by raising hands rather than just randomly being picked has been helpful. Its also been helpful to remind myself that I need to do what's right for me rather than what other people in aa think might be right for me. Sitting in the back early on before I get comfortable in a group can help. I also focus more on talking 1 on 1 with people before or after, rather than the public speaking aspect of it. Speaker meetings can be helpful this way too.
