I take it all back
Okay, all my talk about how I slept so good and feel so great - forget it. It only took physical movement to turn the entire thing around. I'm at work now and I feel like my entire world is full of very thick fog, or very thick soup. My ears are incredibly stopped up - but I'll be optimistic and say that maybe them being so stopped up can serve as natural earplugs during my louder classes. Every part of me aches, I have a severely delayed reaction to everything - I'm totally a space cadet today.
Incidentally, whoever designed my bathroom and put the medicine cabinet right over the toilet obviously never met anyone like me. I've only dropped two things in the toilet so far, and the water was as clean as toilet water can be, but it's just the principle of the matter. Very annoying.
I'm off to try to wander through the fog/soup that is my day.
