Transition or not, you're going to have to confront those fears - otherwise you'll spend the next however many years wondering if it would have worked. I had a chance at age 23 and imploded over a two year period, that was largely due to lack of confidence and lack of professional support...by all counts I was totally passable but wouldn't believe it. I am utterly amazed that my transition has worked this time, twenty five years later, but I really needed to confront my fears about potentially not passing and what it meant to be trans. I had to believe in myself and not be afraid. If 23 year old me could only see me today! But that alas is not a luxury any of us has so we just need to be guided by who we know ourselves to be, denying that self just leads to misery. 🙂
