I know that NA works for some people so I don't want to dismiss it but, I went to a meeting and it was pretty much what you said. People talked about their past experiences, or their shitty day, or their good day, etc. I did not participate in the meeting but afterward one of the organizers talked to me. I said that I did not understand how listening to others experiences would help me to stop using and she said that everyone feels that way at first but that if I started working the steps it would work. I never went back.
