Congratulations in taking the first step. The next step- going back, can be even harder. You will soon feel at home. I have a "home group" and when I was at my most shaken I went to other groups in the area. Each new group was scary but I started seeing familiar faces and heard the same strength and encouragement at all the meetings. Maybe that is an option for you. Different meetings have different feels to them. Maybe another one will be a better match. Give it at least 6 meetings. BUt it sounds like you heard and felt something that was comforting to you.
I had not been on speaking term with my HP for a while. I was angry. One of the gifts of Al ANon was helping me feel closer and soon I was seeing signs that I am being very well taken care of. I hope you have a similar experience. Keep us posted.
