By "primary", I mean ones you truly try to do regularly, that make some positive difference, physically and/or mentally. Of course I realize we do fall behind with some self-care. I'm not so interested in those, in this thread.

* Facial and neck moisturization. Even when I'm neglecting other things, this self-care act seems to remain. At least most days. I tend to apply the creams in a relaxed position (in bed or sitting in a comfortable chair), almost as if part of a facial. It keeps my face youthful-looking and is so relaxing. Again, I could be doing little else, but still do this.

* Sleep hygiene. I work this very hard. I don't just depend on medications. I go to bed and get up at the same times. I take my medications at the same times (give or take an hour), and never skip them. I need darkness and quiet, and the right room temperatures. If needed, I eat a yogurt before bed and/or use my sound machine.

* Achieving the ability to "let things go" and see things glass half full, instead of empty. Sure, depression can make that impossible, sometimes, but I'm not always depressed. It takes work and determination. CBT therapy was quite helpful for me, in this respect.
