How do you stay sane when you have to work all the time?

Most of my adult life has involved lots and lots of work. Right now I’m juggling like three and a half jobs. I “only” worked five hours yesterday because of the holiday. I need to go back to sleep now to get up to be ready for work at 8 am. I’ll be working until 9 pm, with a similar schedule tomorrow, Wednesday and Thursday.

I don’t even have health insurance.
