As sever have mentioned, what you feel is something we all have/do feel this way at times. As for the “passable” thing. Im a people watcher and have noticed, there are GG’s that look no more passable than us. My younger sister for example, if it weren’t for her Double F breast, she and I look about the same. My point is, is really its about our confidence. I haven’t arrived at maximum confidence level by any means, but gaining by the day. I will be starting HRT later this month, so that will be a whole new challenge for me, but im excited about it. Take your time my sister, and take baby steps; it will come when you’re ready.
