Hi hon.
The first time I saw myself and realized this was the path I was on? I don't know for sure, but I think it was before the time I can remember. I do know now that in recent years, as I impersonated a male, when I looked at myself in the mirror as male, I for sure knew that was the wrong path. I had to find a way to the right path. For every one of us that is harder - much, much harder to do then to say. But there did come that day, an hour after taking my first dose of hormones I knew I had found the cross path to the right one. Every step since has been to that path, and now, down the right path. I have found the right path well surfaced, lighted, with gentle turns, and headed toward my future. I don't even know if the path I have followed is even there; I just don't even turn around and look. To quote every TV cop show there ever was, "keep moving, nothing to see there."
As for changes in your mind/soul? I don't think so. The only difference is you are coming out, not pushing the woman back in favor of the man.
