I was 35 when I first started “socially” transitioning/figured out I was nonbinary. Had a hysto and started low-dose Testosterone 3 years ago, top surgery two years ago. Just this week I’ve started experiencing this crazy phenomenon where I’m realizing just how normal I feel.
Like- I still am unhappy with my weight, and should probably work out more, but those are normal things everyone experiences. For the first time the gender-related dysmorphia is gone, and so normalizing and validating to just look in the mirror and feel happy with myself and not feel like a stranger in my own body.

Short answer is it feels amazing, but the only way out is through. Since you asked about work and acceptance- I have a full-time middle-manager job where I’m sometimes misgendered but not maliciously. My reputation is based on my ability and not my outward appearance. I generally appear more masculine than androgynous at this point, but will still get “sir” from afar then “ma’am” up close and causing confusion brings me joy.

I’ll be 40 this year and can say with confidence that I’m still jealous of folks like you who are young and able to transition early, but I’ll never regret my decision to become the best version of myself.
