Good question. It is really hard for us anoners to trust. We must start somewhere and it is supposed to be in meetings. I have gone to meetings, my first one to be exact, where I knew someone, the moderator of the new members meeting. We are told to keep what is said in the meetings there. I would say either go to the Thursday meeting only if that makes you feel more comfortable or go back to the next Saturday meeting and discuss your concerns with the ones who questioned you. You might be surprised to learn they are just as scared as you. They might be able to give you some very good insight. They might even become your sponsor. Who knows, coffee after the meetings have some of the best discussions.
