By May,after three months,I had lost22pounds and reached my goal of 115 pounds.My friends would say “Alice,you look great!”or“How did you lose so much weight?”Those compliments made me feel good and confident.

Soon I dropped to110 pounds.A few of my friends told me that I needed to stop dieting,because I was starting to look sick. They brought me a present—— a bag of chocolates,which I later gave to my sister.My mother would come to my room,with tears in her eyes,and have long chats about how harmful this diet was and begged me to stop.My dad would leave worried messages on my cell phone at school,telling me that it would do serious harm to my body.

By mid-June,when school was coming to an end,I was down to an only alive state of 95 pounds.All of a sudden,I knew I had to do something.I guessed the number itself scared me.I recalled my doctor.He told me about a girl who was 95 pounds and was at the risk of dying.I knew I was putting my life at risk,but for what? To make those who love me worried? Was it worthwhile to be thin?

Now I realize that models in magazines,TV and movies are not realistic.The price to pay for the“perfect body”is living with a dangerous and sometimes deadly eating disorder.And there are more important things to think about than how thin you are.
