WHY CAN'T I DO THIS PAPER?!

So it's quarter to 11 right now, and I had a paper due for class tonight. I skipped class, because the paper wasn't done. I stayed home to do the paper. Only the paper isn't done. I have sat here and done everything BUT the paper, including spending countless wasted moments posting comments and journal entries like this one. WHY CAN'T I FOCUS ON THIS STUPID PAPER?! This is the biggest paper of the course, and its supposed to be about 2,000 words. And its on some stupid case study that's hypothetical and no cares about it but I have to force myself to sit here and make sense out of it. Which continues to be impossible because I have no idea what I'm doing. Frustration overtakes me. I have until 5 minutes to midnight to finish the paper for it not to be late. All I have to do is email it to my instructor. But I just can't get all my thoughts to cooperate. My mind is scattering all over the place. I need to take a deep breath. I need to calm myself. I need to bang this thing out. I need help.
