I caught the beginnings of a headache at work today. It didn't go away. I think it's because I'm so worn out today. I hit the wall in the practice room and class was a fiasco. I'm in a class full of Music Ed. specialization people, very few of who've actually taught (I have, by the way). The prof is giving people a chance to teach and no one's into it. It felt like four hours, instead of the 75 minutes it actually is. I still have my headache.
