For me, it was something I knew at a very early age, and almost started transitioning about 10 years ago, but ultimately let the hard parts (coming out to family, at work, facing discrimination) got the better of me, and I buried it all really deep. But now, it's gotten to the point where the dysphoria and hating this body the way it is are - well, as big as, at least - the fear, and doing nothing no longer seems like an option. It was getting to the point where I was constantly suicidal, and I got tired of always wanting to die.
