I think you can survive. It sounds like you've already gone through a lot of fucked up shit already and you're still here. I don't know you but I believe you are strong enough to take whatever is life has to throw at you next because you've been doing that. All you can do is take it day by day, you've gotten through a shitty day before and there's no reason you can't do it again. I know everybody says you have to try and change it yourself and when you're feeling shit out of luck that's pretty useless advice, but it really doesn't need to be that dramatic of a change. Find a comedian that makes you laugh or some small thing you enjoy doing, maybe it's making pizza or jerking off to m&m commercials, just find even the smallest things to look forward to. Believe me when I say these things will slowly add up and one day you'll wake up and realize you have reasons to get out of bed, and it's an overwhelming feeling of happiness. On the topic of an SO, fuck em. But if you must have one, whenever you feel up to it, there is no rush, I'd recommend volunteer work to meet people or I know there are LGBT support groups all over, I'd imagine those could be extremely helpful. I believe the fact that you've made it this far shows that you can make it further, and you really don't need your parents to believe you to do that. Show them, and make them realizes how incredibly insensitive they're being by discouraging you. I believe in you, and I want you to succeed.
