i have issues of rage related to complex PTSD. rage is nothing to fool around with. i suggest you see a therapist as soon as possible.

my experience is to distract my self from the thoughts that cause the rage. listening to music is my number one distraction. exercising - especially bike riding - also helps. any good hobby in which you can immerse yourself helps. you need to see a talk therapist and find out the cause of the rage and try to defuse it and understand it.
