Thank you for sharing your story.
A few weeks ago, I told my physician that I am transgender - she was the 3rd person to know. I wasn't nervous when she first walked in the room, but my nervousness grew exponentially as it came time to tell her. I gave her a copy of my coming-out letter, thinking it would very quickly answer many of the questions she might have. I'm probably the first person ever to have gone to their doctor with an essay.
She wasn't hostile, at all, but I do think she was "caught on the hop". She's a quite young doctor, and it seemed clear that she had never had an MtF transpatient. I told her that I was interested in HRT, but I don't think she had any more idea how to move ahead with that than I did. In the end, she gave me a few suggestions for transgender therapists.
So the appointment wasn't all that I was hoping for, but coming out to a significant figure like her was a great milestone to pass. It felt good. Since then, I've felt much more relaxed about doing so, and much more relaxed about myself.
I'm looking forward to hearing more of your story.
