Libby

If a genie popped out of my bedside lamp, I would wish for these three things: my mom to be alive, nothing bad or sad to ever happen again, and to be a member of the Martin Van Buren High School Damsels, the best drill team in the tristate area.

But what if the Damsels don't want you?

It is 3:38 a.m., and the time of night when my mind starts running around all wild and out of control, like my cat, George, when he was a kitten. All of a sudden, there goes my brain, climbing the curtains. There it is, swinging from the bookshelf. There it is, with its paw in the fish tank and its head underwater.

I lie on my bed, staring up into the dark, and my mind bounces across the room.

What if you get trapped again? What if they have to knock down the cafeteria door or the bathroom wall to get you out? What if your dad gets married and then he dies and you're left with the new wife and stepsiblings? What if you die? What if there is no heaven and you never see your mom again?

I tell myself to sleep.

I close my eyes and lie very still.

Very still.

For minutes.

I make my mind lie there with me and tell it, Sleep, sleep, sleep.

What if you get to school and realize that things are different and kids are different, and no matter how much you try, you will never be able to catch up to them?

I open my eyes.

My name is Libby Strout. You've probably heard of me. You've probably watched the video of me being rescued from my own house. At last count, 6,345,981 people have watched it, so there's a good chance you're one of them. Three years ago, I was America's Fattest Teen. I weighed 653 pounds at my heaviest, which means I was approximately 500 pounds overweight. I haven't always been fat. The short version of the story is that my mom died and I got fat, but somehow I'm still here. This is in no way my father's fault.

Two months after I was rescued, we moved to a different neighbor-hood on the other side of town. These days I can leave the house on my own. I've lost 302 pounds. The size of two entire people. I have around 190 left to go, and I'm fine with that. I like who I am. For one thing, I can run now. And ride in the car. And buy clothes at the mall instead of special-ordering them. And I can twirl. Aside from no longer being afraid of organ failure, that may be the best thing about now versus then.

Tomorrow is my first day of school since fifth grade. My new title will be high school junior, which, let's face it, sounds a lot better than America's Fattest Teen. But it's hard to be anything but TERRIFIED OUT OF MY SKULL.

I wait for the panic attack to come.

Jack

Caroline Lushamp calls before my alarm goes off, but I let her go to voice mail. I know whatever it is, it's not going to be good and it will be my fault.

She calls three times but only leaves one message. I almost delete it without listening, but what if her car broke down and she's in trouble? This is, after all, the girl I've dated off and on for the past four years. (We're that couple. That on-again, off-again everyone-assumes-we'll-end-up-together-forever couple.)

Jack, it's me. I know we're taking a break or whatever but she's my cousin. My COUSIN. I mean, MY COUSIN, JACK! If you wanted to get back at me for breaking up with you, then congratulations, jerkwad, you've done it. If you see me in class today or in the hallways or in the cafeteria or ANYWHERE ELSE ON EARTH, do not talk to me. Actually, just do me a favor and go to hell.

Three minutes later, the cousin calls, and at first I think she's crying, but then you can hear Caroline in the background, and the cousin starts yelling and Caroline starts yelling. I delete the message.

Two minutes later, Dave Kaminski sends a text to warn me that Reed Young wants to kick my face in for making out with his girlfriend. I text, I owe you. And I mean it. If I'm keeping score, Kam's helped me out more times than I've helped him.
