     During my ninth-grade year, I suffered from anorexia nervosa: it was not enough to be thin. I had

to be the thinnest. Now, however, fully recovered, I can reflect (反思)back and realize that my wishes

were more complex(复杂)than fitting into size five pants. Many of my subconscious (意识)emotions

were related to my relationship with my father. As 1 was growing up,his work always came first.

Sometimes 1 would not see him for up to two weeks. Not only did he devote his whole self to his work,

but he expected me to do the same ("You cannot get anywhere unless You go to the best universities").

Though,consciously,I never felt pressure to please him,I began dieting after the first time he told me I

looked fat.    

     At the time. All I knew was that I had to be skinny--skinnier than anyone else. Every month my

father went to Europe for a week or so and on the days he left,sorrow and emptiness consumed (折磨)

me:Daddy was leaving. Then,I tuned to focus on a mysterious weakness ---a helpless childlike emotion

that came from starving. I liked to know that I needed to be taken care of；maybe Daddy would take

care of me.

     Now two years later and thirty-eight pounds heavier, I have come to realize that I cannot change my

father's inability to express his feelings. Instead,I must accept myself. I know that I am a valuable person

who struggle to achieve and accomplish. But I cannot struggle only for others. By starving,l attempted to

gain pride in myself by getting my father's approval(赞许)or acknowledgement of my value as a person.

But the primary approval must come from me,and l feel safe now that I can live with that knowledge

safely locked in my mind?
