What do you do when you really need a break, but can't afford to take one?

Things aren’t going too well right now. I’m overwhelmed, stressed, confused, disappointed, and kind of sad. On top of all that, I’m sick. I would love nothing more than to disappear from everything for a while, but I have a lot on my plate right now and disappearing isn’t an option.
What do you do when you want to get away and, at the moment, you can’t?
