Hi Tori,
I just told them. My immediate family I invited over for dinner and presented as me, fully dressed. My wife already new and accepted Cindy all our married life. Friends I just told. It's one of those strange things of presenting our selves as TG, it is often less of an issue for others than it is for us, strangely. When I came out to family my sister in law just said, Oh I've known that for years. We go out together regularly for dinner. Her husband has been totally accepting, in fact everyone I have told has been.
And you are a very lucky girl to be on HRT at 19, hope it all goes well for you.
OH BTW if you are that close to your female friend, she probably already suspects. I would invite her for a coffee or some such thing and tell her straight out.
Hope it goes well
Hugs
Cindy
