I found the best course of action for me was to make a coming out video ^^
I have allot of friends and an enormous family (one of my grans had 11 kids! D:) so it was pretty much going to be impossible for me to talk to everybody one to one. Hence the idea to make a video explaining things came up...
Basically, I very loosely explained the condition etc, what it means for me, what it means for friends and family, answered a bunch of Frequently Asked Questions ("What about kids" "Does this mean you are gay?" etc etc) and finally posted a few links for further reading...
It worked out really well!! Like way better than expected!!
In my experience, if you are going to get a bad reaction from somebody, it's normally going to be when you are sitting in front of them, having just blind-sided them with this huge reveal, and expecting a reaction from them right now. Allot of people need time to digest and come to terms with things before they can be supportive, and initial reactions, even just perfectly natural ones of shock or withdrawal, can be properly hurtful, especially if you are in a fragile state of mind.
With a video, you can send them it, and it is almost like you are talking to them one to one, but you are not forcing them to react immediately. If they take a few days to get back to you etc, that's fine. They can come to terms with it in their own time. You don't get hurt, and they don't feel under pressure to react to it right now!
It was the best idea I have had in my transition so far, one click, a post on facebook, and over the course of the week all my friends and family sorted themselves out "behind the scenes" as such, and came to me with love and support in their own time.
I couldn't recommend it more.
