The green worm inside me

Today I feel awfully tyred. Don't know what causes this feeling. Might be the fact that I couldn't sleep all night, or the thought of being free for two months and 1/2. Maybe its the little brain worm inside my brain knocking my ears and eyes. Maybe its green and has two large eyes, moon eyes in fact. Whatever it was, today my head was glued to my desk, all day. My friends thought I was fainting in lunch... in fact I kind of was... My head at least. It was yelling at me, commanding me to stop, and find the nearest bench so that I could curl up and rest. I seriously need to find a way to sleep and not think. I once tried that "trick" some people call, the one when you count and keep counting and then POOF! you are dreaming with angels. The case was different with me, it didn't work so well, I was still looking at the wall when I was past two hundred and sixty five. I also tried reading a book which didn't work so... I loved the book so much I read 'til I finished it...and it was a pretty long night. I think Ive tried everything... including the usual glass of milk, which woke me up to go to the bathroom at three in the morning... I think I have Immsonia.
