Skipping a class

I usually never skip any of my classes but this one if tough. Im a neuroscience major but I have to take english comp. I have a B+, Iv missed two classes (we get up to 5 absences) and my professor isnt super crazy about attendence. Today I had so much homework and I forgot I have a rough draft of a paper due tommorrow. I just cant do it tonigh, between work and spemding 5 hours on homework and preparing for two exams, im drained. I feel awful for skipping, plus im paying for it, but sometimes im just too drained. Should I feel this awful about skipping or am I looking to much into it?
