By all means give vent to your anger, let it out in nondestructive ways--if you are still deciding to have it. But begin to think of yourself as someone who can learn to think new thoughts when you are frustrated, so that the immobilizing anger can be replaced by more fulfilling emotions. Annoyance, irritation, and disappointment are feelings that you will very likely continue to experience, since the world will never be the way you want it. But anger, that hurtful emotional response to obstacles, can be eliminated.
