I'm so confused and scared?

I'm Shelby and i'm 15 years old. I've grown up in a family that is very accepting of homosexuality, but I myself am a devout Christian. I think i've always known that there was a part of me that liked girls but i've tried to ignore it and push it to the back of my mind but it keeps coming up. I'm scared that I will go to Hell and that I won't be accepted in society. I've been contemplating suicide lately because I don't want to put up with my future. I'm really scared, I don't know what to do. Can I cure myself? Please help me. I don't want this life, I want to get married and have a family but that's not going to be possible for me. Just please help, i'm so scared!
