Danielle,
You showed real courage in even partially coming out. Recently, I kind of came out to my daughter by saying that I'd always been a little straight, a little gay, a little bi, and a little trans. She texted me a couple of days latter, and said she wanted to talk. She said not to worry - that she'd known for a long time. So, we had a long talk and I told her that I was transitioning. I explained the HRT (E and Spiro) and what I expected it to accomplish. She was surprised but understanding. She asked about surgery and I said that bottom surgery may or may not happen (I explained the details), but said that I plan a face lift next year along with attacking my beard. It really went surprising well.
I will next have to come out to the President of our Local Union. She wants me to come back into our political arm and I want make sure she doesn't get any surprises. Such as, "did you know that queer went out to the downtown bars dressed as a girl" She will hear it all from me, not from some transphobe.
At any rate, coming out to people that you can trust is a good beginning. Maybe you will find someone else to confide in. I think you will feel more assured as you find acceptance. I know this coming out process is making me feel more confident. Good luck!
