Is this normal? What to do?

Hey I live in S.C and here everyone is a total / hater. It makes it really hard to tell anyone I am gay which makes me feel perminatly bad on the inside because I feel like I'm keeping a real deep dark secrete. I am 15 years old and at my high school I am pretty sure most people would totally shun me if I came out. I told my three best friends and they all took it very well, but I will never tell my parents (they'll catch on someday by their own accord) but idk weather to come out at school because I really want to find someone else that is gay I really feel bad when I can't love anyone because of the way and place I was born. What should I do? is it normal to feel this way? Who CAN I talk to?
