Sorry to hear about your health, & also don't forget to prioritize your health over the game. it'd be pointless if your working in a not-so ideal condition which could acutally hinder the game more than just taking just a break. Take a break!
It's a hard thing to balance really, I tried taking a small break last month but recovery was too slow and there was a lot to do. Now I set up a reasonable way to finish tasks in time but there's a lot to finish in a month, let's hope it does work.
