Chronic illness fatigue just isn't like any other kind of being tired.
It's more like Sisyphus would feel after an eternity of pushing a boulder up a mountain. (Of course, according to the myth, he earned his punishment. We didn't do anything to deserve this.)
We wake up tired and go to bed exhausted, and in between we fumble through life as best we can.
Sometimes, we manage to fight the fatigue and get things done. But that usually catches up with us in the end.
Have you ever envisioned yourself as a patron of the arts, but don't have the money of a Medici? I'm told Patreon is the 21st century way of sponsoring artists of all types. You can be a patron of my writing for as little as $1 a month. (Only if you can afford $1 a month.) Patrons will receive electronic copies of each new book I write.
