For somebody like myself with DID, and a de-transitional journey rather than a transition, this is a tricky question, ha!
But, everything about me has been altered by my de-transition to female. Every outward thing is also different.
When my DID healing recently occurred, and I re-awoke, my first impulse was to acquire some of the same stuff I used to cherish. Now it all gathers dust, I have no attachment to those things anymore, though they are cool, and I still excel at using them, too. I just can't be bothered with anything that once fascinated me for some undeniable reason. So, for me, I learned a very big lesson. I am not the person I was when I was who I used to be, and nothing can make me back into that person. That person was a caterpillar, I am a butterfly.
What remains the same is what many might call my 'soul'. The core being that was born all those years ago remains a constant, but nothing else.
So, no, this journey has stripped away all that I appeared to be, and I am glad of it. What remains was the part that existed before any of the 'wrong me' was wrapped around my true essence. What I have gained is what I lacked all along. I am very, very, very, glad for that fact.
