Insomniac

I don't really understand how people sleep at night... Lately, I haven't been able to get to bed until around 1 or 2 in the morning, and sometimes later. Could it be that I've become such a hardcore procrastinator that I even put off sleeping, one of my favorite activities, until the last minute? Seriously, is that possible?
Maybe it's because I don't want to go to the soul sucking hell that is my high school that I know I have to attend in the morning. Between pre-calculus and the number of people openly bashing and mocking my faith, I've just about had it. I get a lot of weird looks when someone uses God's name in vain and I openly make the sign of the cross when I hear it, and any time I look at my pre-calc assignments I can't help but see Gandalf in my head yelling, "You shall not pass!"
Maybe I'm just mutating into a night dweller and I'll end up sleeping during the day and roaming around the streets at night. The sun is quite harmful to me. I am a ginger after all...
It's annoying because even when I'm fighting to stay awake and my eyelids are getting heavy and I'm almost nodding to sleep every 2 seconds, if it isn't past midnight, I find some way to stay awake a while longer.
Well, whatever it is, it's killing me since I'm 16 years old and needing to wake up at 6:30 every day (Including Sundays). The most I get to sleep in anymore is like 7:30 or 8 on Saturdays.
Sorry if I sound like a pretentious, snobby teenager. I just really like to sleep and I can't seem to do that anymore. Any help on how to force myself into bed at a decent time would be lovely.
