        I had a surgery called radical neck dissection, which is about as pleasant as it sounds. Then radiation.Then they tried some chemo for my lung tumors. The tumors shrank, then grew. By then, I was fourteen.My lungs started to fill with water. I was looking pretty dead—my hands and feet ballooned; my skincracked; my lips were perpetually blue. They’ve got this drug that makes you not feel so completelyterrified about the fact that you can’t breathe, and I had a lot of it flowing into me through a PICC line,and more than a dozen other drugs besides. I finally ended up in the ICU with pneumonia, and my momknelt by the side of my bed and said, “Are you ready, sweetie?” and I told her I was ready, and my dadjust knelt telling me how he loved me in this voice that was not breaking so much as already broken, andI kept telling him that I loved him, too, and everyone was holding hands, and I couldn’t catch my breath,and my lungs were acting desperate, gasping, pulling me out of the bed trying to find a position that couldget them air, and I was embarrassed by their desperation, disgusted that they wouldn’t just let go, and Iremember my mom telling me it was okay, that I was okay, that I would be okay, and my father was tryingso hard not to sob that when he did, which was regularly, it was an earthquake. And I remember wantingnot to be awake. Everyone figured I was finished, but my Cancer Doctor managed to get some of the fluidout of my lungs, and shortly thereafter the antibiotics they’d given me for the pneumonia kicked in. I wokeup.
