Hello, Little One.
I have some tips for you...I was 18 when I had surgery and that's nearly 40 years ago.
Be yourself. Do the things you dream of. If you want to look like your profile picture, then practice.
Look up support services near you on the internet. Go and visit a Dr who will support you. Your parents don't own you, you do.
You will only have this life, and as you get older it will go faster & faster, so make good choices for you, now, and work at them.
Because of your age, you have the choice not to think of yourself as transgender...but as a girl, and a woman.
How you "think" about yourself is very important, just as knowing you are really a girl is.
Practice being you, I suspect you will become like I became...natural!
But remember, try and make good choices, because choices can sometimes be wrong, and you have a wonderful chance to make good choices for you.
You've taken the first step...the world is your oyster!
Hugs and contact me if you need to.
Hope XO
