Що означяє фразеологізм: За мене не розписуйся?

 переведите пожалуста на русский 

At school i do three hours of sport a week. I have always hated sport. When i can, i miss the lessons. This term i have pretended that i have hurt my leg so i don t need to do any sports at school. I even go to the doctor even week to do special exercises for my leg. The problem is that i can t pretend that i have got a problem with my leg all year. I really don t know what to do, i m in such a mess. I really feel so bad about this. What should?
