I also think that when you practice the self-care, even when you aren't "feeling it," you ARE rewiring your brain. One of my favorite sayings in recovery is that it's easier to act your way into right-thinking than it is to think yourself into right-acting. The more you do it, the more you will "feel it"--that's something I'm rediscovering right now as I'm making my place a cleaner, more attractive place to live. I never felt it was worth the bother, but now that I'm "bothering" with it, I'm feeling more worth it.
