A static and solemnly invincible alibi

The moment the cold air rushed in from my open car door I could feel it coming.
The atmosphere was permeated with the smell of campfire smoke and the ominous gray calm before a snowfall. Standing on the front porch I sifted through my bag, searching frantically for my lost key while juggling and dropping my books and violin case. Something monstrous twinged in my stomach as I crossed the threshold and I sat down on the stairs for a minute with my head between my knees.
Leaving school early had been a blessing in disguise.
I stumbled up to my bedroom and shut the door, throwing my books onto my bed. Outside the snow was already beginning to fall, illuminating the room with white light until the sun passed behind leaden clouds and left me huddled in shadows.
I opened my history book and squinted at the section on Louis XVI. The words blurred and once again I felt anemic and queasy. Leaning my head back on the pillows I commenced to daydream and gaze out the window, taking deep breaths and trying to regain control over myself. I watched a Chickadee cock his head at me through the glass as he followed a trail of winter sunflower seeds. My hands and feet were very cold, but my forehead was feverish; already a silver sheen of sweat enveloped my skin, and I could hear my heart racing in my head-- thumpthumpthump.
I closed my eyes.
I had nightmares as I slept. I was lost in a confusing maze of black and nothingness. The emptiness of the space scared me more than the darkness. There was quiet screaming somewhere in the back of mind, successively raising volume decibel by decibel. I twisted and turned until I was hopelessly tangled in my sheets. The screams became unbearably loud. I awoke suddenly and sat bolt upright.
With shaking fingers I stuck my finger with the lancett and drew a perfect drop of blood.
37, the meter read. I had dropped with unbelievable speed.
I drank some grape juice-- greedily and hungrily, still shivering. I immediately felt the heat appease and I dropped off into the state of peaceful rest I had hoped for.
Somebody barged noisily into my room, and stopped short of the bed. A worried silence ensued as I unconsciously felt my mother's eyes rake over my bloodless cheeks and weakened state. I did not open my eyes. I felt her cool hand on my forehead and her lips on my cheek. With the reverence befitting a tomb she backed slowly out the door.
Outside the snow continued to fall.
