What is wrong with me?

Why can't I go to bed at a decent hour? Why do I sit here wide awake though my body is exhausted? I have so much to do tomorrow, why can't I just go to sleep? My sister will prob'ly call in the a.m. and tell me what time they are coming out for a visit and then I will go crazy trying to clean this place up so that I am not completely embarassed. Oh and did I mention I have to cook two cream soups from scratch and some rolls and desert tomorrow and have it to town by 6pm? Guess we'll make up for schoolwork on Fri. since there are no co-op classes. I love how flexible homeschooling is! But really, I just want to SLEEP!!!
