It depends if it's a day my filters are working or not.
I try not to purposely keep things in anymore to be honest. After years of suppressing a whole lot of shit, I painfully learned it all comes back out in some of the damnedest ways.
If my filters are in pretty good working order, I'll try my best to communicate that I'm having a hard time in that moment and need some space/time to process, or else I risk continuing to be triggered and all bets are off as to what comes flying out of my mouth. Then I have "clean-up duty" to have to go through in trying to explain why I lost my shit, and I try to avoid that like the plague.
Mostly, I'll try to choose a healthier distraction to be able to release it based on what's available in the moment, like walking barefoot out in the grass, dig a hole in the ground or in a container full of dirt and plant something so at least something good can grow from my frustration, primal screaming into a pillow or while riding in the car with my favorite music cranked up, deep diaphragmatic breathing and alternate nostril breathing exercises, spend some time in the bathroom telling my reflection in the mirror how worth it I am to not let anyone else take complete control of my emotions, etc. The breath work is like the foundation to whatever else I choose.
