After the disaster with dad, Mom said that I would feel better if I had somewhere to let off steam, so I joined the local gym. I went Every day after school last week. The instructor told me not to do too much, but I paid no attention.I'm still on my diet. I've lost 11 pounds, but it's not enough. If I have a bad day, I do more exercise at the gym. Mom is really worried about me. She says it's not normal to think about food and weight all the time. I know she's right, but what can I say to her?
