You mention meetings, so I'm presuming that you're an AAer. (Apologies in advance if this isn't the case.) Have you spoken to your sponsor about this? I'm presuming that you would have included it in your step 4 inventory work (under resentments?) If not, then perhaps you could do a step 4 & 5 on it with your sponsor today?
Prayers for you to find some serenity today.
And a drink will not help. You know that from past experience. The relief would be the shortest of short term, and the repercussions, quite possibly, a lifetime.
