Physics=my worst nightmare

So I missed my physics review and part of my organic chemistry over the weekend and now I have to make it all up except for the fact that I don't know what I'm doing. Everything seems foreign to me at this point and to make it worse. I keep falling asleep. As my book opens, my eyes close. It's an instant reflect. I don't know why it happens but I now I finally have got myself focused but remembered how I didn't finish my posts yet. So here I am writing about physics and my bad sleeping habits. I need to wake up!
