For a number of reasons I felt overwhelmed the last two weeks with work. Part of it was the academic calendar---I had less time after classes ended than usual. Part of it was taking on some more responsibilities for my professional association. A large part of it was feeling that my being behind was holding back other folk from getting things done.
For whatever reason (hard work?) I've gotten to the point where I am more on top of things. I think that teaching probably helps moderate my anxiety.
