"It is plain that a life which includes deep resentment leads only to futility and unhappiness."
"This was our course: We realized that the people who wronged us were perhaps spiritually sick. Though we did not like their symptoms and the way these disturbed us, they, like ourselves, were sick, too."
"This is why A.A.'s Twelth Step urges that we practice the principles in all our affairs."
"As each member of a resentful family begins to see his shortcomings and admits them to the others, he lays a basis for helpful discussion. These family talks will be constructive if they can be carried on without heatedarguement, self-justification, or resentful criticism."
"Giving, rather than getting, will become the guiding principle."
"We are not living just to be sober we are living to learn, to serve, and to love."
I could be wrong here, but you're probably going to need to do more than just pray if you want to see any headway. More means communicating with your sister. It might be helpful to have an unrelated 3rd party involved to assist with the flow of the conversation.
Letting Go is a lifelong process, one that only ends when we "let go" of our earthly bodies. And life is far too short to hang onto all those resentments. If you are looking at your resentments, you are not looking to God. I've had to deal with the usual familial resentments and more, not once but twice I was replaced at work with a student that I had trained myself. Because the managers' actions in both cases threatened my livelihood and my family's wellbeing as a consequence, I had to deal not only with the resultant resentment but a real fear of the future.
The only answer is to look up. The only person being hurt by your resentment is you. Emmet Fox, who inspired Bill W. had this to say about Noah's Ark, that it had only one window and that window looked to the sky. When we are surrounded by a deluge of troubles we need to look up. It is not necessary to cosy up to people who have wronged you, only to let them go from your thoughts and when they reappear, you must not look back but only ahead. Treat your resentment with prayer and try to see the Big Picture. Yes, your little sister (or brother) has broken your favorite toy but a loving Father will not smite them just because you desire it so! Their path is theirs to walk and your path is to focus on your own life, knowing that in the end, these people really have no power over you.
