Izumi: I would not believe that the two people are the same. The transition is remarkable. Wow!
Melody:
I do not know the details of your marriage, but I am sorry. Hopefully, it is for the best. At least, you will be your true self and have someone who will love you, for you, all of you.
I understand how you feel about passing. I also still see a boy (male), when looking in the mirror. I especially see a boy, when I go out to eat and see women. I feel more masculine than Arnold Schwartzenegger. Yet, I understand that I am changing, slowly but surely. I do get people using male pronouns, but I get female ones too. At the temple where I go, I asked about joining the women's club and nobody batted an eye and everyone calls me by female pronouns. Okay, this one kid a few weeks ago, about 5 or 6, stopped me and asked if I was a girl or a boy. I did not know what to say, so I obfuscated. It is happening.
What I am realizing is that yes, I am not female looking yet, but the real transition is that in my head and that takes time. Being a female was always this dream, not a reality. "Believing" is what takes time. Then again, seeing a penis, male pattern baldness, deep voice, male forehead, and narrow hips does not help matters.
You will do fine. You are on hormones and they will and do have an impact.
Congratulations Melody!
