You know how 95% of trans people think transition is absolutely viable for everyone else, but not for oneself? You know the "I'm too old/too masculine/too feminine/too bald/too tall/too short/too muscular/too petite" merry-go-round that your brain puts you through?
It's always more viable than you think. It's not even whether you can pass well or not. Transitioning is better than not transitioning even when there's very little initial progress. It just feels better. It makes you stronger. And changes will follow anyway.
I thought I was the one exception, too. Well, guess what.
