<human>: Can you provide a brief rundown of the text in within 3 sentences?

I came out to my  family three years ago, when I was 14, as transgender. My parents are separated, so I live with my mom and brother, and only visit my dad once in a while. Pretty much, the family that I live has been super okay with it, and I haven't had any problems with them (except for a bit of confusion from my brother, but that's done now). However, my dad has realllly not been nice about it. He has never really acknowledged that I'm female, and only consented to letting me start estrogen after about a year (thanks dad -_-). 

Now that it's been three years, I'm starting to get more eager about living full-time as a girl, and it's also getting more complicated to "cover things up" (like body changes, having to constantly take pills). Everyone in my family except for my father is on board with me transitioning, and really just don't care. My dad, on the other hand, has made it pretty clear he will disown me. Now, normally, this wouldn't be a problem. If I could just say, "fuck you" and never see him again, that would be fine. But, that's just not the case. 

If I do transition, my entire family will completely fragment, because my brother and mom have said that if he's gonna keep being a prick and disown me, they'll stop seeing him too. I feel like if I do go through with this and finally transition, my brother will be deprived of a relationship with his father, who he is kinda on sorta-good terms with (it's complicated), and will make things weird with him and my mom, who will still have to communicate with him about legal stuff after this. I really have no idea what to do. I don't want to break up my family, but I don't want to have to keep living so uncomfortably.
<bot>: I'm transgender and if I complete my transition I'll break my family apart. If I don't, my life will continue to suck.
