Hello my dear friend!After reading your letter, I felt like you feel bad.You're very tired and I recommend to you a good rest, because it is so important to protect your health. Yes, good grades is very important, but you need to take a break sometimes.Your friend ... I think you need to talk to him frankly. Discuss the problem, tell each other about their experiences, and there, and everything will look.Your parents ... Oh! In adults, ever so many problems ... But do not worry, everything will sooner or later all will be adjusted. And remember, even in bad weather, there is a ray of sunshine. Everything is super ... and good luck!
