Sobern, I go through what you described from time to time. The resentments and bitterness builds up. It dominates my mind instead of clear, spiritual thinking. And if I don't catch it before it's too late, I don't necessarily think about drinking, but rather I burst out and get in trouble for things I say at work or with family.
Just wondering if you've done a fourth and fifth step lately? I know for me when it really builds up, my attitude gets bad, it's time to do a fourth and fifth step. That means writing down on paper my resentments, fears, and my own selfishness. Then sitting down at a table with my sponsor or another AA person I can trust, and sharing those defects with them. It truly does relieve a lot of that tension that builds up and I feel better. Good luck.
