Good day Zab, there is a line in the Big Book which reads, "We no longer regret the past, nor wish to close the door on it" that is one of the many promises of sobriety I hold onto.
The biggest hurdle is getting there.
I believe Step 4 lifts some of that burden and step 9/is where we find freedom.
If you are not into AA, then Hazeldean publishing has a tremendous amount of non AA resources. One I bought for my husband is "12 Steps for Men" as both book and study guide. They also have one for women.
You can order direct from their website.
