I need some serious help with uality?

Neil, you're going to be fine. Just take a deep breath. You don't have to come out to anyone before you're sure about things and you're sure you're ready. You can wait until after college if you want to or your whole life. It is possible that you are just infatuated with this guy and you're not 100% gay. Give yourself some time, you're not working against a deadline. Make your life as livable and as happy as you can. Don't torment yourself. If you like somebody, like them, be happy from it, the whole school doesn't have to know about it, you don't need their approval for love. So far as your family is concerned, don't be too quick to judge them, they might surprise you. Watch them for awhile and if you want to come out to them, make a strategy, with a plan B or C. Strive to be happy!
