Where is the energy they promised? I say: false advertising.

So whats going on when a 15-year-old girl starts (literally!) falling asleep as soon as she gets home from school? I understand being tired (6:15 am- 10pm five days a week) but I thought I got a few years of boundless energy and all-nighter capability before I got older. I keep taking unwilling naps on school days! I actually moved my bedtime back to 10 from 9:30 because my parents told me I was getting too much sleep and couldn't wake up during the day. Now the only change is I am sleepy all day AND fall asleep when I get home. This is so aggravating. Most teenagers stay up till 12ish, get up at 5ish, and don't eat breakfast, but only a few subside on Red Bulls and Starbucks. The people who don't seem to have more energy than I, who goes to bed at 10 and eats a huge breaksfast.

Ok, sorry for that rant, but I just had to take a shower at 6 pm in order to wake myself up.
