Self-care
My idea of self-care has come down to four very specific things.
Taking up the sword, making art, singing, and never taking a phone-based customer service job ever again because retail customers are trash and no one in the service industry gets paid near enough to be verbally abused on a daily basis by people with petty concerns who ratchet up your blood pressure and PTSD. There was never anything good about doing this work; not the pay, the expectations, a fair amount of the workmates, the customers, the management. Nothing.
Well, one thing was - when I stopped doing it.
