A Feeling
It's the kind you feel in your insides, where your tummy feels horribly empty. There's an odd feeling in your toes and the tips of your fingers, and you shiver even though your room is supposed to be hot and your only form of ventilation is a gentle electric fan. It's where you want to put your head in your hands and cry, but save for a piercing feeling in your eyes that lasts for a moment, nothing comes out. Where you want to hide under your blanket but you can't sleep, or you sleep but get no rest, because you are fitful and your dreams are exaggerated continuations of your anxious thoughts. They bring in your subconscious too, so all those fears you couldn't put a name to come out and mix in with your conscious worries in ways that defy physics, common sense, dimension and continuity. Then you wake up and feel like you haven't slept a wink, but the clock says it's been several hours since your last waking thought.
