Yes, I disowned everything. I sold off my boy stuff to help pay for my switch, and I am glad I did. I have no use for those items or activities nor the feelings that they stir up. I changed my name, location, and attitude about everything.
I am in the 'stealth' camp. My past is my business, and mine only, and I want nothing from it to taint my present or future. I am living soft-stealth now, as I do have family in this area that know everything, and my doctors know, too. Beyond that, nobody knows anything, and no internet search turns up anything. I was very, very careful about how much I put out there, and it has paid off..
I know my approach is not right for everybody, for whatever reasons, and that is cool, we all need to do what we need to do. BUT, living without being compared to my past self, or past accomplishments, or past relationships, has allowed me to heal MUCH faster than if I had tried to 'convert' my past into a better future. Leaving it all behind was therapeutically correct for me. For others, it might be an emotional disaster, so I say this stuff with that in mind.
Even with only a few loved ones and doctors that know my past in my life, I still feel compromised emotionally. Even though they all know I was born female (I was a mis-gendered XX female), I feel the gravitational pull from that old life pulling at me. When I lived in deep stealth in another state a while back, I felt no such pull, and the wind beneath my wings was sooo refreshing and freeing and happy, happy, joy, joy...
Just sayin', that is how it is for me.
Hope this helps.
