Here's what I've noticed...  If I'm talking with someone else I know, I will probably not seem much different.  People have told me I seem 'happier' now in conversations and how I behave.  I'm only dressing as male as much as required by situations.  I guess if anything, my personality is then 'happier' when I'm female.  Other than that, I really and about the same person.   But that's not quite true...I do feel like I can be a better person and try to shed the negative aspects of my former male self.  But I'm not pulling any 'Jekyle & Hyde' routine, aside from perhaps feeling better and maybe that shows.
