I just came out to my family about 2 days ago and one of my brothers was extremely combative, inappropriate and confrontational about it all. He was pretty much demanding that I get multiple second opinions from health professionals and that telling me that I didnt know "->-bleeped-<-" and had no idea what I was getting into. And worse.
Worst thing of all is that I really look up to him, so getting all this thrown in my face was pretty damn harsh you can imagine.
Of course, I was upset, but I also started second guessing myself which was worse. The only thing that I had comfort in at this stage was that I had finally figured out where I was at and this was destroying my sense of self. I had finally found myself and wanted to share it with my family and not exclude them from this huge part of me, were I not to I would be lying to them (Besides, they'll find out something is up when one day I have boobs, speak funny and dress nicely). I got away from it all and basically told him to come back to me when he was able to talk to me like a real person. He did. His views didn't change much but at least the screaming and shouting stopped.
We have all been through a hell of a lot and the last thing we need is to be second guessing ourselves or feel the need to justify our "choice" to the rest of the world who quite frankly will pretty much never understand why.
Stay strong, remember how you got where you are, how you felt when it first clicked, how you feel when you are you and not the person that others say you are, it brings it all back.
I really hope they come around Sky-Blue.
