Immaturity

My favorite way to deal with unpleasant situations is avoidance. I don't deal with overwhelming stress in a mature or professional manner. Thankfully, due to avoidance , that doesn't happen often. Though, the other day it happened. I threatened to quit and, maybe to keep me on staff, my boss let me have my way. Unfortunately, by doing that, a good friend was punished for my misbehavior. Now my heart hurts because of what I did to a good friend. A friend so upset I thought he might even cry in anger and frustration because of the entire situation. I may have lost a friend because I can't control my anger at times. I am not happy with myself and am not sure how to fix the mess I made.
