Again, bravo, Brianna.
That you are looking forward, with an eye towards how you will deal with practical issues like housing and employment speaks volumes about how well grounded you are, in the reality of the path before you. Transition is as much, if not more, about those things than it is about clothes, cosmetics, or physical changes.

As for passing, you may be one of the lucky few who eventually will. The odds on that are long indeed. The unfortunate truth is that those of us who've been "deformed" by testosterone, genuinely passing, all the time, is impossible. As you've already discovered (and seem to have gracefully accepted) though, is that it doesn't really matter. Most people will at least be polite, even when shocked. More and more, we're not even "shocking", novel perhaps, but even in those cases, when their mouth closes up and they can speak again, they will observe the decorum appropriate for the situation. But then you seem to have already discovered this and perhaps even made your peace with it. Well done.
