Sleep. Bringing our grades down, but it's not our fault.?

Sleep.? If you don't get to sleep for eight hours is it true that you have trouble working in school.? Well, right now I feel pretty tired. I couldn't do any work in my first two periods. It was too hard to keep my eyes open. But it wasn't my choice not to sleep. I had too do some cleaning, babysitting, and study. The stress of being a teenager these days are unreal.. Yeah, your probably going to read this and say "Oh yeah, just another teenager trying to sleep through class or find a reason for bad grades. But, I don't have bad grades the lowest grade I have is a 'B' and if I wanted to sleep in class I would be doing it right now instead of writing this. Trust me I would love to sleep right now, but I can't because I do care about school. I just so tired I feel like I need coffee which people my age shouldn't really drink it. It makes your teeth yellow, Gross. Well, comment and give me your opinion if you think sleep is a big issue on teens and their grades. ----->xoxo, Kayla Marie<-----
