I get absolutely shitfaced. I am shitfaced and hyper and ten years old. I am having the time of my life.

I do not remember very many things from the inside out. I do not remember what it felt like to touch things, or how bathwater traveled over my skin. I did not like to be touched, but it was a strange dislike. I did not like to be touched because I craved it too much. I wanted to be held very tight so I would not break. Even now, when people lean down to touch me, or hug me, or put a hand on my shoulder, I hold my breath. I turn my face. I want to cry.

And so I am feeling numb. It's a curious feeling, and I get it all the time. My attention to the world around me disappears, and something starts to hum inside my head. Far off, voices try to bump up against me, but I repel them. My ears fill up with water and I focus on the humming in my head.

Crazy isn´t always what they say it is. It´s not always the old woman wearing sneakers and a skirt and a scarf, wandering around with a shopping cart, hollering at no one, nothing, tumbling through years in her head. No. Sometimes it is a girl wearing boots and jeans and a sweater, arms crossed in front of her, shivering, wandering through the streets at night, all night, murmuring to no one, nothing, tumbling through the strange unreal dimensions in her head.

My god! people say. You have so much self-control! And later: My god. You're so, so sick. When people say this, they turn their heads, you've won your little game. You have proven your thesis that no-body-loves-me-every-body-hates-me, guess-I'll-just-eat-worms. You get to sink back into your hospital bed, shrieking with righteous indignation. See? you get to say. I knew you'd give up on me. I knew you'd leave.

It is, at the most basic level, a bundle of contradictions: a desire for power that strips you of all power. A gesture of strength that divests you of all strength.

• Eating disorders are addictions. You become addicted to a number of their effects. The two most basic and important: the pure adrenaline that kicks in when you're starving—you're high as a kite, sleepless, full of a frenetic, unstable energy—and the heightened intensity of experience that eating disorders initially induce. At first, everything tastes and smells intense, tactile experience is intense, your own drive and energy themselves are intense and focused. Your sense of power is very, very intense. You are not aware, however, that you are quickly becoming addicted.
