I'm writing about weight problem I had. I always weigh seven stone. And I wanted to stay that way. But a year ago I put on weight. Half a stone to be precise. I was worrying about my weight. I started to exercise madly and to cut down seriously on the amount of food that I ate. At home I didn't eat much dinner but in the mirror I still seemed fat and I hated myself. For school my parents made me a packed lunch every day but each lunch time I always gave it to the birds. Once my teacher phoned my parents and told what was going on. When they found out they were so worried about me. I didn't want to let them down. I tried to eat more but I couldn't. I realized that it was serious when I collapsed. I was taken to the hospital. I feel much better now. The worst is over. Қазақ тіліне аудара аласыздар ма?
