What's wrong..

I can't seem to stay awake past 8 pm.. I'm falling asleep... I can't figure out WHY! I went to bed at 8pm last night and woke up at 7 am, went for a hike, then to some thriftstores, then an engagement party and I'm dead tired. I'm fighting falling asleep so early but I can't help but shut my eyes for a few minutes here and there. My hair also sucks since I moved in here, I can't do anything with it. blah, blah, waah, waah.
