"Are we the same person after Transition?"
I pray every day that I will never ever be "That" person. Over several decades I slowly, inexorably morphed into a 'Thing' I could never want to be as a direct result of my beating myself, my true self, into submission of some 'ideal' I was told I needed to be thanks to accident of birth. Once I started 'Transitioning', once I started to let go of that and figure out who and what I am, I live in dread of 'reverting'
In a much broader philosophical sense, If you are truly alive, you are growing. Transitioning is like a growth spurt. Even if it is just coming out to yourself and wanting to fix how you view yourself in this crazy, and angry world of ours. My core values are still the same as that "Same Person" I was before. A few belief systems, much needed then to survive, have been tossed aside since I began 'Transitioning'. Since I began growing again.
I am the same person. I am a far more joy filled person. I am not a farther worse person as a result of my constant, all consuming, battle to keep Joanne locked away in the dungeon.
