This is a hard one for me, being a driven person who constantly feels the need to be "doing something" -- but the truth is, sometimes you need to give yourself a break.
If you're like me, the characters and plots in your head can wear you out. If you're an insomniac they can seem like a pleasant distraction until you start to crumble. That kind of stress is not good for anyone. With a chronic illness like late-stage Lyme disease, not being able to rest/sleep is a HUGE trigger for setting off a flare-up.
This week I've had to tell myself I'm on "sick leave" before things get worse. I have a book currently in review by the senior editor of my line. I don't need to kill myself cranking out another story right this minute. I need to let my head clear and my body rest.
Because sometimes that's the only choice.
