One way to get your anger out in a constructive way is to write her a letter. Write down all of the anger and the hurt. You may hold on to it a couple of days but I wouldn't say much more and then burn it. Let the anger go away with the flames.
I know it sounds simple but I really think it will help. Wjhat do you have to loose except some of your anger?
