Something that has helped me in the past is what psychologists term 'Sublimation'. It's a healthier and more productive defense mechanism than just venting or taking your anger out on the person who provoked it. In a way, I think this is what tfish08 was doing with the blame game.
I tend to use the gym or sport as a way of redirecting bad/ill feeling regarding my W & OM. Creating art, music or writing are other ways to sublimate during those darker times.
Do you have a hobby to channel yourself into, perhaps something you used to do and could pickup again? Or, find something new via your GAL actions.
Wishing you better days ahead.
