Jitters

So its about 28 hours before the final draft is due. I am sick to death about turning in my paper. I feel like this is my wedding day all over again. My nerves have completely taken over my body and I have no idea what is happening. I will have a nervous breakdown if I do not get an A on this paper. I have worked so hard night and day to put together a fantastic paper. I felt like i was doing a prolific dissertation for a bunch of med students lol. I just want this to be over and for me to get my grade. I am so close to an A in this class and I do not want to mess this up. So much anxiety...aaarrgghh. Thanks for letting me vent and ramble on and on.
