....gay?

Hello, I am a 14 year old boy living in Italy and I have a secret that I never told anyone ... I am gay. Well nothing so upsetting but for me it is completely upset my life and will involve the lives of my friends and family I'm afraid for when I'll come out. I am afraid that everyone will move away from me because not everyone has an open mind and some think that being gay is a disease and I'm afraid of this how people will judge me I do not have many friends and no one who can trust me is very difficult as it was for many people. What should I do?      -Kevin
