I've not come out publically or to everyone close yet. I've told most of my open-minded and closest friends (well, I'm not generally close to any closed-minded folk) and a couple of cousins but not anyone in my immediate family. I've also told a closed forum I'm on, online.
I wrote a private, anonymous blog and I gave people access to that, where I'd explained quite well what was going on. I'd invariably also talk with them in person and while a few were challenging in that they sort of challenged whether I was correct or not and kept raising questions and saying that "everyone is like that" to most things I'd say, eventually they realised and accepted that this was something altogether different. Everyone has been supportive and while it was hard to hear the challenges, it's understandable enough so I don't take it personally really.
Most of my immediate family will be easy. I've already come out as an atheist, which was difficult but I am an open person and couldn't not let them know. My dad is the difficult one. He's a Christian who feels that homosexuality is wrong, though he's not so bad that he'd restrict their rights or anything. He says it's unnatural, which I'm sure he'll probably think about me now. I was diagnosed bipolar, the symptoms of which I had for 6-8 years and turned out to actually be caused by a temporary vitamin B12 deficiency, which actually seems to have cured it. But he wouldn't believe that and thought he knew more about it than me or my psychiatrist and he's just very black and white about everything and his religion blinkers him. One of those people. The rest of my family are Christians but they're far more open minded to not knowing everything in the world already by virtue of their beliefs so they'll probably accept it. They're constantly laughing at how girly I can be anyway so it shouldn't exactly be a surprise.
