increasing stress?

Last semester was one of a continual sense of impending doom (doctoral exams). This semester, post-exams, has oddly been just as stressful if not more. Instead of feeling like I am going to fail an exam, though, I feel like I'm living a frantic life where I can't get anything done at all. Teaching three classes and working a steady part-time job while trying to do my own research (unrelated to any of the above work) sucks ass.
