Why. WHY?!

Christmas vacation is over, I can feel it in every inch of my body. I'm starting to stress, I get less and less sleep and I can't seem to concentrate on the things that I am supposed to be doing. Like now. I have a maths assignment due about the one theme I that might singlehandedly make me flunk this subject- can you tell it's a draining one? It's probably because of the fact that my teacher wants us to describe everything. EVERYTHING.
