Tall women are awesome!
Trans-femm bodies are beautiful.
I've met several wonderful, beautiful trans women (both pre-app post-opp, no-opp, and most importantly no-one's-fucking-business-opp).
I don't think your situation is easy, my heart goes out to you and your family as you transition.
Being a tall trans woman is perfectly normal and wonderful.
My girlfriend is 6foot3 as well (also trans) and she is gorgeous! Tall women rock!
