Can you feel it?!

I feel the urge to write, but I don't know why, which probably means that I shouldn't write at all because it will come out a jumbled mess. I just googled "jumbled mess" and this is what came up, which is kind of cool. What a great analogy for the mind, or for my ideas. So this is what is inside me right now, and every day that I am not writing, I am trying to piece together some idea or sensible argument for or against something or another.
As a final thought: Explain this to me: Why is it that I enjoy skipping days when working and attending school, because I feel so insanely stressed out, but when I have more than one day off in a row I start to get insanely depressed?
