Hey, I have a story of forgiveness which I think confirms the research that forgiveness is good for your health.
I held bitterness and anger towards my father for years, causing me much grief and distress. Resentment built up to the point where I was physically ill, unable to hold down a job and make significant friendships.
Eventually I made the choice. The decision to forgive came after much soul searching. Almost overnight I felt much happier in myself, was able to improve my quality of life and my self confidence increased all because I courageously forgave my father. Forgiveness releases the power of the offending individual. There is no other thing in this world that is free and can help so many people.
