Try to tell your worries to Dr Know if you have any problem. It can be a problem about your looks, abilities, likes or dislikes or personality.

示例：
Dear Dr Know,
I have some worries these days. I'm shorter than most of my classmates, and I am not good at running, so I can't join the school sports meeting as my classmates do. Also I am a shy girl, it is really hard for me to talk with strangers, and I don't have many friends at school. I hope you can give me some good advice.
