I have been an angry man for a few years and now in the last couple of months, my rage has decreased a bit that the burning passion in my anger has expired. I still feel resentful and bitter on what happened to me that caused me to be angry during those few years. But I just don't feel furious as much as I used to.

Did the passion for my anger burn out or something else is the reason why I just don't feel wrathful compared to earlier this year?
