There is ABSOLUTELY NOTHING wrong with being bisexual, you cannot help who you are attracted to or love. I struggled with my sexuality for a long time too (I'm also bi) cos of my homophobic parents making me think it was something bad and I struggled with hating and hurting myself for it too but I overcame this and accepted who I am and now it never bothers me at all, I barely think about it- it's just a fact about me I can't control like I can't control my hair colour or skin colour. You deserve to be loved no matter your sexuality and you deserve to have love, romantic love as well, just as much as a straight person. I'm sorry that you think your parents won't accept you- I know mine won't either, but it's your life, not theirs. If they truly love you, they will eventually accept you. And if they don't ever accept you, I'm sorry, but they're not worth it. But I wouldn't tell them about it now as you're still dependant on them as a child, wait until you're independent and safe. Another thing, these feelings you're having about your sexuality will never go away, hating and hurting yourself for it will never make you feel better, it won't change who you are. It's better to make peace with who you are.
