What I get out of this entry is that you are sure this is the right path yet a familiar theme has emerged in that family does not condone or is accepting of your gender dysphoria. Since you seem sure that this is the right path then I would say you need to find friends who are supportive along with seeking out a local group that you can talk too. What you don't want is to go through this alone if at all possible and I speak from experience that came from others along with allowing others into my life. One can only hope that given time all or some of your family will come to embrace you as you were meant to be, a female and that you have no choice in this matter. One of my recent things was joining a car club, a fresh start with people who don't know I was formerly male and find me not only meeting up every Saturday for coffee and a drive but also getting together with other members during the week. You might consider doing something similar like joining a bowling league, a book club or something similar that when doing so decide if it's right to expose yourself as a male on the path to becoming a female where of course your comfort level of (hate to say this) of passing dictates how you present yourself. Best wishes on moving forward to blossom into the woman you are meant to be.
