When you have to shell your real self because you are around someone that doesn't know the real you, is not fun. Be who you are, even if you lose that friend. If they are a true friend, they'll love you no matter what. You're still the same person after you tell them you're gay. Love yourself, and be proud of yourself. You are someone that matters. Don't ever let someone tell you that you don't matter, that's bullshit! You are loved, beautiful, amazing, unique, just perfect. People are perfect in their own way. You are unique. Don't ever forget it!
