I use the Spoon Theory!
www.butyoudontlooksick.com/articles/written-by-christine/the-spoon-theory/I MAKE time for funny things. It can be a funny book (Janet Evanovich is my fav) or a humorous movie or a YouTube comedian. Laughing is a great medicine.
I laugh at my own antics. When I get that brain fog and put the coffee cup in the refrigerator instead of the dishwasher, I take the time to laugh at myself.
I also cry when I need to and was great at taking naps! I babied myself and found out I like it.
