Dear ...,
I am so sorry to hear that you are being bullied at school for having pimples on your face. However, don't be pessimistic because I have some advice for you.
The most important thing is to be confident. No matter how bad your friends are, keep calm and stay positive. To do that, you have to improve your face skin condition first. Wash your face regularly and do not touch it as our hands are very dirty. Besides, I know a medical center that is very good at taking care of the skin. If you want to have treatment there, reply my email then I will send you their address.
I hope that my advice will bring some kind of confidence to you.
Write to me soon,
Best wishes,
(your name)
