Learn To Forgive

 Recognize those people who you have not forgiven, and forgive them. Especially the ones you do not want to forgive. 

Release your resentment, your anger. Consider this - what is the reason for holding on to this pain/hurt/anger? For me, I sort of wanted them to suffer. But did they? Did the fact I was angry with them for years keep them up at night? No. They went on living their lives.

 The only one you are hurting by holding on to this anger is yourself. Why should you continue to suffer? Call them and tell them that you have held resentment (or whichever emotion) for x years, and you are ready to release it. Disclaimer: this is terrifying. Remember that one of two things could happen -- they are nice about it, or they are not. 

If you can release your attachment to the outcome, you do not have to let it affect you adversely, and therefore it loses scariness. Pray
