I just want sleep! (FC)

Last year began the downward spiral that is my life. Since last year the most sleep I've gotten so far is about 6 hours. Last year was so intense mostly because of AP chemistry and US history, those two classes killed me. I would come to school on barely any sleep, and even on absolutely no sleep which is just complete misery. This year I get a little more sleep but not enough, and I have noticed how it has negatively affected me in school. I find myself forgetting a lot of things that I wouldn't have forgotten two years ago. This especially worries me in math because that's what I want to do with my life, and it requires memorization. Not only is it affecting my memory but it's affecting my ability to pay attention. I might think I'm paying attention, but when it comes down to the work I realize that I actually have no idea what the teacher said. I think that maybe I should work on better time management skills, so that I can get the right amount of sleep.
