Resentments were what fueled my alcoholism (the BB does say they are the number 1 offender for alcoholics and I found that true for me).
The solution to deal with my resentments are the 12 steps (steps 4-9 in particular). The steps are a spiritual solution. And if you work steps 10-12 on a regular basis you'll find it's a really good way to keep your resentment list short on names.
I might me wrong here Realest but it sounds like you may have a couple resentments bubbling up yourself, either at the program or at a few people in the program...my guess would be the latter. Maybe time to put some names to paper and run them through 4-9?
