@seesaw, good question and I don't know! Count to ten? Take ten deep, very slow breaths? Take a brief or long walk and come back to it? Distract myself with something positive & come back to it? Eh. Who knows! I'll try all of the above.

To answer your question though, I don't have a strategy in mind. Perhaps something for me to research further. I am proud of myself though for not losing my cool very recently over something I was triggered by, and instead, I drew firm boundaries (because people were crossing them) and I kept my cool. That was progress.
