Taking and making time for self-care is so very important and much underrated IMO. How are you supposed to work, help, teach, you-name-it if you have no energy left?
It must be hard and hard for me to imagine not knowing when you have electricity and working around it but - you are doing it, you are succeeding. So, yes to

be grateful for what you have and keep going, no matter how difficult it may seem.

Keep on going, Ernesto and keep your beautiful cats a cuddle from me. Luna has, indeed, interesting coloring.
