Congrats on your weight loss!!!
Sounds like it's time for a bra fitting.
I call this "stink eye" which is what I get when in guy mode and my hair is down. Here's an oldie-thread from before your time here Anne...

What you are describing is something which transcends what I call a moment of being.
A moment of being happens when you are out and presenting as a female and something almost magical happens. Everything seems to be in it's right place in the world. Your confidence soars. You might capture a glimpse of yourself, see a blurred reflection in a window, or even see your shadow, and all you detect is woman rather than guy or trans. And if your really lucky, these moments will leak into your interactions with others when again, it becomes all about NOT being defined by your trans nature. Moments of being are also enhanced by something as simple as a song, smell, or even weather. You cannot plan these moments, they have to just happen. And when they do, you know you are really on to something special.
Transcending these moments is when you perceive the woman without presenting as such. In my case, the body mods I have made for the sake of my own being often lead me to the same place you have experienced, where you see female in the mirror instead of male. Call it psychological tricks, call it delusional, whatever...it's real, at least to me.
And to think you have found this in such a short time. It's taken me years to find this place of absolute bliss.
ps - If you have any doubts whatsoever about the reality of such moments, ask my buddy Suzanne, she's been there and done that as well.
