Not too many people can embrace the 12 steps so thoroughly, my dear.
Alcoholism runs in my family, and I have seen my siblings go through the steps, but not let go as you have. They did not backslide, thank God, but they held resentment.
Only my mother, one of my sisters, and I escaped the disease.
Gotta go to the Big Book on this one: "It is plain that a life which includes deep resentment leads only to futility and unhappiness. To the precise extent that we permit these, do we squander the hours that might have been worth while. But with the alcoholic, whose hope is the maintenance and growth of a spiritual experience, this business of resentment is infinitely grave. We found that it is fatal. For when harboring such feelings we shut ourselves off from the sunlight of the Spirit. The insanity of alcohol returns and we drink again. And with us, to drink is to die."
Note the three death threats in there. Resentment will kill us.
