Welcome to the forum, Jessica. All of your questions have been answered here somewhere - just look around.
> In general, your breasts will grow to about the size of your sister's, or perhaps a little smaller.
> The facial hair does not fall out.
> Your body hair will get more sparse (probably) and of finer texture.
And for the other questions, you'll have to do a little research, here on the forum and elsewhere.
Again, welcome.
