You have as much potential as you let yourself. If you decide to transition, it's easier when you're younger, especially if you have body issues. It's tricky critiquing people's images, and I think it's easier if you know that whatever decision you make, we will accept you. Transitioning isn't easy, but it can be very rewarding.
Yes. Every day you have the chance to change and reshape your life to better suit your goals and potential.
Do you have the determination to follow through on your goals?
Best of luck, no matter your decisions, and give yourself a hug from me (I always feel better after a hug),
