Stuck!

I am so frustrated at the moment! I thought I new what I was doing with this paper, but now I feel like I have been thrown for a loop! I must admit that I get confused easily with this assignment. Normally in the past I could see very clearly what I needed to do with writing assignments, but for some reason this semester I feel like I am in a fog. I just can't seem to get out of it, and I feel very lost!
I was working on my thesis tonight, and I thought I had something good. Then I realized that my argument was not sound. So I am back to the drawing board, and time is running out. I am glad I caught it while I still had some time, but at the moment I am tired and I do not want to think. I think I will try to read the story again and then sleep on it.
