So that's what it was...

... that restlessness, the energetic yet slightly depressed feeling: the Flu. Come on, I never get sick like this! It's my thing to be on-and-off sick for weeks before actually catching a cold. And now, all of a sudden I have a fever :( This sucks. The weirdest thing though - mentally, I still feel very energetic, it's just that staying up too long makes me feel dizzy.
