I can strongly second this. Anytime we can make the world see us as we see ourselves we gain freedom from worry and peace. Isn't that what confidence is? I am so much happier now. The part of me others see is female where before only I could see that.
It reminds me of she used to come out to the world. The person in the video is her as she sees herself, but others and the mirror show her current outsides. We all take small steps toward that every day. Painting nails, waxing eyebrows, feminine hair cuts, hrt effects. Some of us may not feel we need as much to match, but for those of us that do this is a HUGE leap forward.
