Hi Mona,
Sorry my response is a week later!!
Clearly you already have anger in you or you wouldn’t be consumed by it. What I would do is listen to what I call “Victory Anger” music. i.e. “I’m a Survivor”, “We Are Never Ever Ever Getting Back Together”, “It’s Gonna Be Me”, etc.
Every day sing and dance to it. Get Angry! Feel Victorious! Then, in every day life, you will be surprisingly calm.
Best,
Inky
