Just keep getting back on that horse. When I'm in a downward spiral, deciding to do just one positive thing (like eating a good breakfast) and giving myself permission to not be perfect with anything else just yet helps me get back on track.
I love your list - how do you feel about long walks? A long walk in the woods always helps me - even if I don't feel like walking, I tell myself that I'll take the shortest trail and walk as slow as I want. It always works.
