Lolz99: In the world I grew up in, there was no such thing as transitioning. (I was born in 1962). I did not find out it was even possible until I saw Dr. Renee Richards on TV when I was 19 (in 1981). At that time I was a broke college student, and back then, health insurance didn't pay for anything. You paid cash out of pocket for the whole deal including therapy and hormones, if you could even find any hormones.
I tried again in 1989 after I finished law school. But back then "gender identity disorder" qualified as a mental illness. So, get diagnosed as mentally ill, goodbye law license.
I tried again in 1999 after the end of my first marriage. But I knew then if I came out, I would lose custody and visitation of my kid. So I waited until he grew up.
By then (2009) I had been suffering panic attacks for five years. I held out another five on the same basis you did. I was a good looking, popular, successful alpha male.
But the panic attacks caught up with me.
If you can be happy being a guy, good on you. But be advised, it may have health consequences you are not aware of at your young age.
At this point for me it is not about being beautiful or sexy or passable. I've been on hormones for a week, and the anxieties, worries, and panic attacks are gone. That alone was worth the price of admission. However girly my body gets, I'll make it work some way or another. I figure I am going to need some nose and forehead work at the very least to make my face passable. And my voice ranges from male baritone to gender neutral on the high end. So maybe I will never be passable. But I have already found the peace I am looking for.
Just remember, you are very, very young. And if you are truly transgender, this is a decision that has not been permanently made. It is one that you will be revisiting periodically for the rest of your life.
