Don't let your anger or rage go unchecked. When feeling hostile or enraged, deal with it as early as possible. If you don't, it can be so painful that you will feel like you want to use just to put out the fire. Anger is sometimes unavoidable. What you do with it and when you do it are under your control. If you know it's a common problem, say a prayer in the morning asking your Higher Power to keep you from emotional upset as you go through the day. Take breaks throughout the day to breathe slowly. If something triggers it, and you feel offended or insulted, tell yourself to relax because if you act out in anger you will suffer the consequences you have suffered before (like alienating friends, spouses, children dogs, etc.) Follow the rage through to its bitter end by remembering how hung over and exhausted you are after a hateful attack.
Before doing that angry email or hurtful attack, take a break, do something else, then reply when not irritated. If you feel compelled to do something, don't.
