Clenched teeth. Definitely a certain shakiness or vibration type of of feeling. Breathing speeds up. Tightening of my neck and shoulder muscles. Sometimes a fidgetty tapping, rapping of fingers. Depends.

I can either type it out, voice my thoughts to someone. I know how to bring that elevated anger off. Much like grounding of an anxiety attack bring myself to take deep breathes, close my eyes a quick meditative technique or two. Count to ten or higher.

Or if necessary, keep myself still/calm look straight ahead focus on my facial expressions to hide it.
