Why does life always get in the way?

I am currently sitting on the floor of my new apartment surrounded by boxes. I have been moving furniture all day and my back is killing me. The problem is that my big certification exam is in two days and I cannot find my study guide anywhere. I am so exhausted that I just want to sleep for a week. The stress is so high that I actually caught myself wondering if I could pay someone to take my PMP test just to survive this mess. How do you guys handle life and studying?
