I need some guidance... desperately. T_T.?

Dont just run away.. maybe casually ask your parents what they think about gays and see how they react? if its badly, try maybe going to another family member about it. But if you are sure you are gay.. don't try and live a different way.. that's unfair to you and your future wife adn children. You wont be happy being yourself and that will drive you absolutely crazy. If it comes down to you telling them, be very straightforward about it, dont beat around the bush and tell them who you are. If it makes you feel more comfortable, have someone there with you, an older family member, a friend, because idk about your parents but mine dont get mad and yell half as much as they do when someone else is there. Just disappearing is also a very bad idea, because moist likely, it will end up as a police case or who knows what else. Stay strong and good luck!
