Upset

I'm very upset about something...
During the summer when I was taking an intense writing course, I wrote all the time AND it was good stuff. Amazing stuff. Since school started, I have not written much, and when I do, it isn't at all good. I can't seem to find my center - the place where the meat and potatoes writing comes from in me. I'm beginining to wonder what happened. Why can't I seem to get to the spot where my most emotional, raw writing comes from? I almost feel cheated somehow. It's like something has come and taken my muse away. And I want it back. I need it back. It's my lifeline.
