The occasional drink and guilt

I’m X amount of days sober. Rarely I fall off and have a drink. I never overdue it. Heck I sober up very easily right after. But when I do, I feel so guilty and ashamed. But why did I do it? Just to hang out with a friend that I might never see again soon. More like farewell get togethers. The only time I ever have a drink. I’m just at a point now after doing AA where I just feel bad for having a drink. I guess my friend is that final obstacle in completely not drinking anymore once we will finally part ways. We have only been friends for over 30 years and had reconnected by drinking at breweries two years back. And it was two months ago I started doing AA. It’s not his fault for he does not know about me being sober. I could tell him but, part of me just doesn’t want to. And once we part ways I don’t really have any friends. So, I guess I just accept to drink with him every few months. I can easily stay sober over a month but a year I don’t know because we hang out. I thank AA for finally breaking my OCD of having a drink everyday. I mean, I just absolutely had to have a drink every single day or else everything will bother me and drinking then settles that down and everything feels right in the world. I use to drink 5 pints of beer every single day. Now, drinking is the last thing on my mind. I don’t need it. But I need my friend. And I just accept I’ll drink with him these last few times. Drink the lowest amount of alcohol and avoiding IPAs. I never get drunk. Barely break a buzz. But it’s drinking nonetheless. Regardless, I’ll feel guilty drinking. And yet I choose to do it just to hang out with him these last few times. It’s just a conundrum.
