I completely understand the desire, even the need, or natural tendency for pieces from the past to fade away and feel like a different person. I look back at my early years in college, when I was very religious, and very conservative and I shudder at some of the things I said and did - it really does feel like a totally different person compared to who I am today.
When it comes to transition I can definitely see how this also would be the case. There is a lifetime of "acting the boy part" because it's what I knew I was supposed to do. So I completely identify with the likelihood of certain aspects of my behaviors and attitudes from the past fading away - like many of my old behaviors and attitudes from my early church life have. I've gone through a couple of paradigm shifts in my life that have radically changed the way I think and relate to the world (non trans related) - so I can see how details from the old chapter can form a sort of dead aspect as if from another life.
By the same token though there are things that are consistent about me that I've brought forward, even from childhood to today. My sense of humor, the personal satisfaction I get in being a "helper", and my interest in philosophy to name just a few.
Actually, the idea that my future self might be so radically different from my past that it feels like a dead person makes me worry a little about myself. Maybe I'm reading more into these comments than I should, or taking this the wrong way. Like, is it normal for a trans person like me to feel like I'll be the same spirit/soul after transition? Certainly I can easily say I look forward to having as much of the "male" baggage that I've had to carry my whole life be lessened or removed, but I also realize that tied up in my past as a "boy" is a bunch of wonderful memories with beautiful people.
It's not easy for me to think of transition as death when I think of all the people who have helped sustain me through life. I have so much gratitude for those and the memories we share. I don't hate my life (I've learned to even accept some of the pain as part of my journey.) I really only would change one thing if I could from my past - my gender. But just because I wasn't the right gender doesn't make me resent my past for some reason. Is this normal?
I like what Helena said, I can identify with that. And I think others have said they experience many positive memories from the past, but sort of remember themselves as the "correct" gender? Maybe I'm taking this all the wrong way and everything is fine
