I tend to "rehearse" the things that make me really mad, go over them again and a gain in my mind until they whip me to a frenzy. I really have to work on finding ways to not do that. Either to get onto the old "mindfulness" discpline whlere you let the thoughts come and go without puttung any emotional weight on them, as if you were just putting them on cars ans letting them travel off without jusdging them, or by not even letting myself think the thought more than once. It's hard either way, because it is, after all, a habit, and the rage is like a type of high and it kicks in very fast. By the way, how is your anxiety?
