Emily you are beautiful.
You're facial structure is very natural

making yourself believe you pass mentally makes you pass more than you think you do physically.
It's easy to question every angle and every tedious thing that defines the gender we wish to convey
Just be easy on yourself and focus on loving and taking care of your body opposed to trying to figure out whether you pass or not
and Stop Hiding who you are!
I think a lot of your worry is stemming from still only being partly yourself publicly
after 3 years you deserve it sister
