"Taught me that resentment only hurts me and not the person I resented, that was really needed at the time"
You don't need the watchtower books or their "ministers" to learn that. All you need is a working brain and some honesty with yourself. If that doesn't work get non-religious self help books. But mainly stay away from cults, which create a very appealing image to draw you in, and later abuse you and exploit you.
