Eventually one just has to let go of anger. It’s a very corrosive emotion, and if it ravages unchecked for too long it leaves holes in one’s heart, holes through which all the good, happy emotions in life will leak.
I still get angry sometimes. I’ve had a lot to be angry about lately. A lot to be upset about. But I make an effort not to stay angry. It’s just not worth it. Anger renders the perpetually angry incapable of happiness.
And I am actively pursuing happiness.
