Please, help me, I am gay and need help?

I am gay, I dont get turned on by girls, however my mother does not believe me, she hates me for it to say the least, she always tells me that I am an "Abomination" or a "Sin in god's eyes". I hate to say it but I have been believing her, she thinks this "Gay" Stuff just recently started it and it is an act. But it is not, I have been attracted to guys for the past 4-5 years now and I am 14, before I was about 10, I didnt know what sex was, and therefore never "lusted" for either gender, but then after I understood "Oh, so thats what it is" I've been lusting for boys rather than girls. I am going into my freshman year of highschool in a month or two and I dont know whether to hide it in school, let it out, or just keep it to myself and if someone asks, just to tell them. I feel like my emotions have had a major disconnect in the past few months, which was similar to what happened about 2 years ago. I am not saying my life is horrible. My emotional and Sexual life is however. I am a virgin, but I cannot picture myself being with a female, it doesnt feel right, I masterbate to pictures of males rather than females and enjoy that kind of thing 20x better. I have contemplated suicide many many times but I dont want to, I just want to be accepted. I dont have many friends maybe 2 or 3 and then my entire 8th grade life, EVERYONE in school hated me through 6-8th grade for being gay. I only have maybe 9 or 10 friends now that believe in me and support me through this ordeal including my sister, Stina. She is very supportive and is "kinda" Bisexual. She knows how this is, but when she told my mom, my mom was fine with it, no questions asked. But when I told her about 1.5 years ago, she pretty much hated me for it and GROUNDED me from cpu, xbox, phone, going anywhere, tv, everything, for about 4 months because she thought it would magically turn me straight. Please help me, I need friendship and prayer more than anything right now. ~Leo Masaki~
