I've had a few days (literally, three total) where I thought I didn't want to transition anymore. Not because I don't want it, just because it would be so easy to just switch to pretending to be female. People wouldn't stare at me and wonder what gender I am, I wouldn't practically have an anxiety attack every time I went out in public due to not binding, I'd save tens of thousands of dollars, I could start living life and not feel so "stuck" all the time...
But then I remember what it was like before I started transitioning. As messed up as my life is now, what with being stuck in-between genders for an indeterminable amount of time (money issues), it's still better than living as a "she." Yes, right now I'm sort of just "stuck," but at least I'm not headed in the complete opposite direction of where I want to go. It's not exactly progress, but it's not complete failure, either.
(note: I'm talking about me and my experience. In no way do I equate any pre-transition people to be "failures." No offense intended to anyone.)
