Can you go in your room, close the door and start pounding on your pillows? Does that help? Have you tried it? Maybe that will START the release of the anger. If it does, then keep pounding and start screaming & yelling, and holler at whomever you're mad at! I do that, and boy does it help! I visualize the person I'm mad at, and the pillow becomes that person. LOL I pound the living daylights out of it. LOL
It really helps me. My therapist told me to do this. Works for me. Hugs, Lee
