Yes. I killed my former self many times over to get to where I am now. I don't bother thinking about childhood anymore because it feels like someone else's life. I don't miss it, since I didn't like the person I was then and worked hard to be who I am now. My childhood was far from ideal anyway, being at the mercy of a violent alcoholic parent and living in poverty and with my own extreme anxiety and depression. Not a whole lot of joy there to miss.
Just decided to start my life from a new point, living how I want to and not how they made me live. I may have had an unhappy childhood but I can do whatever I want now, and if I want to have another, in a sense, I can.
What made me dysphoric was being excluded - excluded from what I thought was the life I should have been living. Not to mention my own body. And the nasty truth that - no matter what I do - I will of course never have a completely normal life or be completely free to have one. Still, there are things that can be done to fix at least one of those.
