Most of us at one time in our lives have been wronged. We cannot control what others do all we can do is control how we react. Many have been hurt by another, and some have never truly let go and forgiven that person. Reflect on any anger or resentment you hold, who is your anger benefiting? Them or You? Write a letter to the person who you are angry at, you can send it or not but just putting it down can be cathartic. Write, reflect and try to release this anger, do this for yourself!
