Hell, not trying to fight the angry and bitter has left me in better shape than trying to be all "forgive and forget." It's a lot easier (and better, I think) to go, "OK, so, I'm angry and hurt" and accept it than beat yourself up trying to make peace with it--it's like, we're not taught how to take the bad with the good.
Yes. Not saying that forgiving isn't good when you're ready for it. But your feelings are what they are, so you might as well acknowledge them. Be aware of them (I would say something about "acknowledge them with mindfulness" here, but I don't know how much yogini-speak you can handle), acknowledge them, accept that they are what they are, but at the same time don't let them rule you. (Fine line, I know, and I'm not claiming I'm doing perfectly at it myself, far from it.)
It's more about making peace with yourself than making peace with the past.
