Dear.........
I just got your letter and of course I'd be happy to help you. A lot of teenagers fee the same way as you and there's nothing wrong with it. Here are some things you can do to help yourself feel better.
First of all, you shouldn't worry too much about your weight. Your body changes a lot at your age because you are growing. It might be a good idea for you to start doing some exercise. This way, you'll keep fit and healthy and help your body grow in the best way possible. Another good idea is to try to follow a healthy diet. By eating healthier foods, you will lose weight and also provide your skin with the necessary vitamins to look healthy and bright.
I hope my advice helps and everything turns out for the best.
Let me know how it goes.
Claire
