You have a normal guilt about getting with someone who is in a relationship. But, I think your recent break up makes it feel like you are being the type of person you ex was unfaithful to you with. Ergo, you almost feel like you cheated in your old relationship, even though you were and are single. You feel like you broke it up, almost like you cheated on your gf but were also the one she cheated on you with.

Self care would be exactly that. Stop judging yourself. As you said, you dont have a serious problem with alcohol, you know you arent the same level as the others at the AA meeting. So, listen to yourself.

It sounds like you’ve over-reacted and you’re trying to locate something to help you. But, removing alcohol wont change it, we all have silly memories associated with it, good, bad, ugly ones.

Probably you’re reacting strongly because of some other issue in your own life, or past. That’s whats making you do 100 in the slow lane with all this guilt about a minor event. So, calm, and focus your attention elsewhere before you get obsessive about what happened.

The hardest thing? You’re making yourself feel this way, and only you can remember you have a choice. Its not alcohol, its not what you did, its your own mind running away with itself. We all do it, but remember you are in the driving seat! Take a break and remember yourself.
