Everyone has regrets, even if they are not problem drinkers. It is natural to have them. Having been through an outpatient rehab program, I can tell you that if you were to tell the group and/or therapist you have no regrets or shame, no one will believe you, it's not possible.

It sounds like this has to do with denial and not any issues with morality. Having regrets is a sign of our human-ness and denying having those feelings is a sign that maybe your illness has taken over your life. Which means you are doing the right thing by continuing to go to therapy. I encourage you to keep an open mind. Woody Allen says that 90% of success is just showing up. So, keep showing up. I wish you well.
