Being hurt by someone, particularly someone you love and trust, can cause anger, sadness and confusion. If you dwell on hurtful events or situations, grudges filled with resentment, vengeance and hostility can take root. If you allow negative feelings to crowd out positive feelings, you might find yourself swallowed up by your own bitterness or sense of injustice.

Some people are naturally more forgiving than others. But even if you’re a grudge holder, almost anyone can learn to be more forgiving.
