Your only option is to manage or ideally eliminate your dysphoria but that can be a balancing act in the best of times, and I know some transitioned people who still experience it. The only way is to start at self-acceptance and go from there.
Even today I feel pangs of doubt about where I am and, although I have never been more right in my own skin or more separated from needing to please the outside world, I am still keenly aware that I form part of a tiny and greatly misunderstood minority. So, I juggle thoughts and doubts and stumble along as best I can by applying adjustments to my thought process that will stabilize me more. Within our community we are all different and no one solution works for all. There are too many variables at play, and we must weight a series of benefits and risks to arrive at our destination. I am a big believer in trial and error and doing the minimum before you take large leaps of faith into the unknown.
Some of us have the advantage of being younger while living in a more tolerant world and yet that visibility comes also at a price. Hiding in the shadows was painful and yet it kept some of us from the unspeakable harm that some face. It seems there is no perfect solution, but the best ones lead to some semblance of mental stability.
That is how the “fixing” must happen.
