I am not LGBT myself, so I can't speak from my own experience. But I have seen a few friends come out and it hasn't always been easy. For one of them, it was grand - his family had guessed a long time ago, he didn't dare telling some of the new friends he got after his family moved at first, but now he is in a happy relationship that "everyone" knows about (it's on Facebook and everything) and he hasn't gotten any reactions as far as I know. For the other gay guy in my close cirle of friends, on the other hand - his family is very religious, he grew up in a cult. He broke it off with them in his teens because he 1) realized he was gay and 2) realized he didn't believe in God (or at least not the God they preached about). He's had some serious problems with it, friends cutting him off, etc. His parents know and it was hard for them at first, but they're dealing with it - they don't want his grandparents to know, though, and I know it really pains him that his parents are embarassed about who he is and that he can never be himself around some of their family members. What has helped him is that his parents have accepted it and support him, even defending him to members of the cult etc., and that he has plenty of friends standing up for him. The best of luck to you!
