Hey Patman,
well done
I would strongly suggest working those steps with someone who has already done so
or, if that won't work for you for whatever reason at least listen to the Joe and Charlie tapes at silkworth dot net and work the steps along with them
I didn't think I had resentments either, I say down in a therapists office and she had me yelling, crying, sobbing, snotfaced angry in under ten minutes
It's about knowing which questions to ask and which rocks to turn over, which with solitary self appraisal we literally and mathematically can't do, since as Einstein says we can't fix whats broken with the same thinking that caused the mistake in the first place.
