I've not told any of my family yet, but given that I'm already seen as the outcast in the family, I'm not expecting anyone to react positively. The vast majority will most likely not only take it badly, but become malicious towards me once they find out, and my best hope to be accepted is my big sister who will definitely react poorly at first, followed by every stereotypical question in the book, and then who knows. I started mentally preparing myself for this the day I finally admitted being trans to myself months ago. Thankfully, my wife's family is much more open minded & accepting. It's important to remember that you are doing this for yourself because it's who you are, and the people who refuse to accept this don't really factor into this equation. That being said, you did an incredibly brave thing coming out to them, but while we've had years, sometimes decades to come to terms with ourselves, this is the first they are hearing and it will probably take some time before people come around, even if they are initially supportive. If keeping them in your life is important, then work with them, help them, provide resources and support information.
