Take care of yourself. Your success will come. But it’s not the end game. I’ve never had shingles, but I have Crohn’s disease and cancer, and I’ve had insomnia and back pain and I know what it’s like to feed your health to your ambition.
Take your rest and get some good meds, try a meditation app and ignore the guy who’s suggesting heroin.
Then, when you’re better, continue to write honestly. I predict a brilliant future.
