It's awful. There's no way to describe it. It's like you're empty. But you're full. Full of the emptiness. Full of empty, hollow nothingness. It feels as though every movement, every smile, every word will take your last atom of energy and you will simply burn up, crumple in on yourself, become unmoving, unresponsive. You want so desperately to block out the world, but cruelly you are more aware, even when you are totally unaware. You don't hear, or see, or taste, or know, but you know. Everything is overly bright, happy and alive, while there you are, empty, full of emptiness.
