You, and the rest of us too, will never achieve total change. It's like proving a complex theory, such as evolution or the origin of the universe. There is only evidence moving towards proof, and no absolute proof is possible. There is only moving towards total change, or accepting a rung lower on the scaffold. We all have to come to grips with the fact that I will never have an hourglass figure, menstruate or bear children. I will never have been raised as a girl. If I was always going to be unhappy that I can never achieve total womanhood, I probably should not transition. But I can achieve suspension of disbelief and forget I am not totally 100% female, so it works for me.
