I think the most important thing to remember (for me anyway) is that you don't have to give up your dreams because of how you identify. I want to be a historian, a college professor, travel, spend time abroad and so on, and that doesn't change just because I want to transition so that my body will match my mind. I don't feel that I will ever have to sacrifice my dreams that I had as a straight woman at all, because in the end, she is me and I am her, just now I am me without all the filters. I may have to work harder for my goals, and I do fear it sometimes, but I also welcome the challenge. I think it is normal to worry about the furture, given the current acceptance of transfolks. But then, with the current state of the global economy, everyone is worrying about their futures.
If it makes you feel better, my husband/partner's friend is an actor and living in New York. He is hampered by the fact that he is a short guy, so he can't get leading male parts, but from hearing his stories, it seems to be common place to have men play women's role all the time. There are even voice trainers that help the actors pass as women on stage.
I know some people choose not to transition because they worry about their futures. I think in part it all boils down to how much you want to follow your dreams. If you choose to transition, then yes, things will be different. Only you can decide what will work out best for you. But I think it is important to remember that you never have to give up your dreams. After all, everyone has dreams, don't they? It is part of what makes us human.
