Postpartum obsessions

A half-dozen times a year or so, at the end of a writing project or a teaching term, I follow great exuberance at finishing with a crash of worry (not depression really) about the quality of what just got released. Today, the last day of class, I started worrying while walking to the bus mall: did they learn anything, was I too boring in class, will they take away anything they can use later? This doubt is short-lived. A moment or hour or day or several days later I've forgotten all about it, and my mind is somewhere else. But it's an interesting phenomenon to experience, observe, and think about.
