Why is it so much easier to hold onto anger than it is to forgive?
Holding on to anger can be a way of feeling in control when others treat you in such a way that it is all too easy to feel out of control. Also, the anger can give a person a sense of power, specifically power over others. Further, anger can become a habit, even if this is unintended. This habit can be very hard to break. Forgiveness has been shown scientifically to break this habit of anger.
