One morning you wake up and open your eyes. Your head feels like it weighs way too much, so much it hurts to move: you feel a throbbing behind one of your eyes, or in your temple. A sharp pain, a steady ache. Your brain hurts, as though the fluid between your brain and skull is thick and inflamed. You feel mildly nauseated and you can’t tell if you need to eat or if eating would make you sick. Inside, everything feels jittery and loose, like a car with bad wiring.
