What do you do when you're having a really bad week?

You know, the week where everything just seemingly goes wrong. When everything is out of your control, and nothing works out in your favor (like when the cat is sick and costing you a fortune, and you’re unemployed and don’t get either job you really wanted).

It’s so easy to just shut down and hope that next week will get better… I’m wondering if any of you have advice on how to keep your spirits up, and get the motivation to not just sleep until the following Monday.
