How Do You Get Writers Block on a History Paper!?

Grrrr! This isn't Doctor's Who related, but i'm hoping that typing something will help me get this essay out. Its worth half of a test grade, the other half was a multiple choice test that I took friday. I studied for hours every night to get the multiple choice section right and I think that I got at least a high 90% on it, but that won't be worth anything if I flunk on the writing. Ughh! 

Thanks for listening to my rant. :-/
