Wow, a lot of replies. Well, I checked in on the thread before I went to bed last night, and tried some stuff, and it was kind of successful.
First of all, I took the pillow that's been in the rooms only tiny pillow, letting a leeeetle bit of light leak into the ream. Why was there a pillow in the window? I don't know. Second, I put my alarm a good distance from my bed. I was able to wake up with the alarm at 10:00am today, but I will have to test this further to see if it's reliable. I had to fight the overpowering urge to ignore the alarm and I'm not sure if my willpower is strong enough.

The reason I stay up until 2:00-3:00am is because I don't get tired until around that time, and if I try to go to bed before I get tired I end up laying there for 2 hours and getting aggravated that I can't fall asleep. I don't want to take sleeping pills or anything to remedy this, I'd rather just fall asleep when I'm tired.

@Evil Bob: My bed is literally a mattress on the floor, so no matter where I put it I have to stand up, basically. (Unless I put it on the floor, I guess)

@Climbtree: you're right, I really do not have anything to do all day, but if I sleep too late, like Dada, I will have a headache and just feel really bad throughout the day. Generally if I get more than ~8 hours or so of sleep I will wake up with a headache.

@Coxswain: I can't drink coffee. I've tried and it's just not possible for me to drink more than a few sips. Stuff is nasty. Also, I've quit drinking soda/caffeine in general recently, and my house isn't well-stocked with that kind of stuff. I don't know any 'healthy things' that help you wake up, though!

So here's my plan: I'm going to continue setting my alarm about 5 ft away from my bed, on top of my dresser, and see how effectively that works. If that fails, I'm going to try to find myself a way to get to sleep faster (without pills!) so I don't have to stay up until 3:00am (maybe exercising more will help me with that? I do try to go outside and do things for about an hour every day).

Thanks for the suggestions so far, guys!

Rajew do you sleep with a tv on or anything?

No, I can't really sleep with any distractions like that. Noise, flickering lights, it's just too much.
Okay, so today I set my alarm for 10:00am (I actually stayed up a bit later than normal so I probably should have set it later), and woke up for the alarm BUT apparently I turned it off and set it back for 10:30am, at which point I did wake up and took my shower/take care of my rabbit and I've been up and un-tired since. Maybe if I can somehow make myself reset my alarm every morning??
Or maybe just put a little more effort into my hour of outside time...
