I haven't found a foolproof method of releasing that anger, before turing it inward. BUT- a big help for me is to let out intense energy by going for a power walk. If I could handle running, I would do that! Jump rope, sit-ups, push-ups, etc. I wouldn't advise weight lifting until you gain better control over the emotion and simply focus on what your body is doing.

That is my unprofessional, experienced advice
