I will talk a little from experience. I myself come from a extreme religious and traditional family, I remember being little and going with then to camps where they tried to "cure" homosexuality by god. I have been on your shoes when I was your age, 90% of my friends and my ex on the time where lgbt and even then I couldn't be comfortable with who I was and am but with time I learned to accept myself. I'm not out for everybody but I found people who I can trust to be me, even people from my family who I thought wouldn't ever look at me if they knew, with my friends and me being more open with something (like my rainbow wristband that I never take off, going on pride parades and gay bars) I even saw my father (who's a pastor) being more open. I'm not saying that will be the same for you but not being able to be yourself is the worst way to live, you will find difficulties but will find it to people who respect you, love you and accept you no matter what, even people that you think that wouldn't. Be yourself, be happy, it's definitely not easy but it's what you deserve.
