My routine seems to be "ignore everything until I can't anymore." Most of the time I'm so spent doing what's required of me each day that I just sink into a low-power mode until I'm needed again. Which is pretty often...so I don't have much free time for self care. No amount of sleep I get seems to change how much energy I have, my joints and back are in terrible shape (genetics) so I can't do much exercise, and I often feel guilty whenever I enclose myself into my own little world with music or gaming because my son wants to be a part of my life. What has been the best for my mental health has been reconnecting with my faith life and converting to Catholicism. Generally I just get the impression no matter where I go I just have to make myself available for whatever God needs me to do. So me making plans tends to not matter in the end lol
