Don't want to work on a Sunday night

It's gone 9pm on a Sunday night, and I'm working. Or rather I'm trying to work. Or... I'm sat in the library surrounded by papers that I haven't read, idly procrastinating while I pretend to write this essay that's due in this week that I've barely touched and wait for OtherHalf to call me and say it's time to watch Grey's Anatomy. I'm so unbelievably bored... (and tired) How am I going to get through this term if I'm losing the will to work NOW?!
