Never let anything stop you from achieving what you need to achieve in life. You might not be able to get there right now due to your current circumstances, but the time will come when you'll be able to spread your wings and do whatever you need to do.
You mentioned in another thread that you live in a rural area where it's unlikely you'll get the support you need. Well... unless there's a force-field around your town, you'll eventually be free to leave and find more supportive people.

You're already very pretty, with plenty of potential. Besides which, there are loads of cisgendered women who are a lot less good-looking than you and it doesn't stop them from being women, does it?
So don't worry. Just be yourself. After all, nobody else is going to do it for you.
