I Am Bisexual, But I Haven't Told Anyone.

I've know ever since I was 12 years old that I've been attracted to both guys and girls, but I've never told my family or friends because I'm afraid to, I don't think they would accept me afterwards, they'll treat me like I have a disease. Most of my friends are Christians and think that if you're gay or bisexual you need help, that there's something wrong with you, and my parents wouldn't accept me either, I was talking to my dad and he said that my brother's ex was disgusting because she was gay, but she's bisexual and I told him that he said if you're bisexual you're still gay and that it's wrong, but his cousin's gay and I reminded him of that he said it's different because he's family and I asked him what he would do if me or my brother was gay or bisexual and he said he didn't want us to be that it was ok for his cousin but not for his children which is very hypercritical, so I told him that and he said that he couldn't control his cousin because he's not his child, but he could control his children, which made me feel very hurt, and uncomfortable.
