Can't Sleep

I lay sprawled out on a bed that doesn't support my body, blankets twisted around my legs. The fan sputters in the corner as I toss and turn. It's too hot... No, too cold... I break out in sweat and wipe it off my clammy forehead. Opening my eyes is pointless, the darkness is so dense that I can feel it pressing down on me from all sides.
My legs are burning up, my arms shivering, my torso somewhere in between. No position is comfortable, and I have yet to find one that is.
Tick, tock.
The clock ticks above my head, marking the third hour of this nightly struggle. Nothing I try works, and I'm going to be exhausted beyond measure tomorrow.
No, I'm not sick. Please ignore the large, visible bags under my eyes resulting from disease we like to call insomnia. Yes, I am paying attention. What did you say again?
Everything is blurry and hazy, all because I can't sleep.
