I have started to forgive, but sometimes my anger gets the better of me. I get so angry that I lose focus. What would you recommend?
I would recommend first being aware of the increase in your anger and the degree to which this is happening. Then I would reflect on how the anger itself is compromising you and your health in particular. This can be a motivation to exercise your strong will to continue forgiving. As you continue to persevere in forgiving, then the anger will not be controlling you, but you will be in control of your anger.
