I feel like my life has been on an upward trajectory for the last 10 years or so, so in response to your question, no, I don't miss the "old" me. Neither do I hate old pictures of me, though. Looking back, I sort of feel like I really made a good faith effort at pretending to be a man for many years. Had I kept at it, I imagined that I'd have been a better one. But my thoughts on that are shaded by my acceptance of who I really am. What it really means to me is that as a man, I would have been more like a woman. In the end, I'm finding that I didn't know anything about how to be a man at all.
There are quite a few old photos that I like to look at now, that captured important moments in my life. For a long time, I couldn't even look at them. I discovered much later that this is known as dysphoria, the same thing that wouldn't allow me to look at myself in the mirror. Now, I have no trouble checking myself out in a mirror, either.
I like your thought about "old" me protecting me, as I went through my pupal stage, right?
