One of the best things my T taught me was about ebb and flow of our energy, we're like weather or tides :-) and moods and energy come and go. Now it's a bit more comforting to me to watch and see that's true and not something that is my "fault" when I'm not feeling as energetic or in as good a mood as I was "before." The old airline admonition helps me too; you put the oxygen mask on yourself first and only then help others, including children, around you. If KD isn't doing well, she can't help the others as well! Take care of yourself. Hope you are getting some good R&R finally.
