School tests or homework? I basically have the same problem as you... and to make it even worse, I have a cold or something. -.-
You're not the only one with that feeling. I have a urge telling me to go finish my stories, but I have no motivation and little time to do it. It's actually a little annoying... There's also another 'voice' telling me to go spend time with my friends, but I don't want to, since some aren't online during this time of day.
