I answered Probably not.
I imagine if I were born at least 100 years ago I would have been deeply hiding all of my symptoms. If I were catholic, I probably would have joined a monastery and tried to be secluded and purge those horrible thoughts that made me unworthy. As a protestant, I am not sure but still would have felt (as I had till not too long ago) that I was wrong, unworthy and full of guilt. I don't know if I would have been able to mentally survive. However, like others have pointed out, I don't know that I would have realized it was an option to transition or at least just assume the role of the other sex. I think it would just have been seen as odd or evil. This is all assuming that my heritage was generally the same(western European).
