Like Dena said, a lot of people look at those who have successfully transitioned and forget that they have gone through hard times just like you. At least you're in the process of doing it, your family is aware, and they aren't disowning you for it. Sure they may not be as supportive as you want them to be, but this is probably extremely difficult and new to them as well. They are going to miss the person you once were to them.
I went through a dark stage of depression a couple months ago and had constant suicidal thoughts. It's hard to be transgender in a society like this to begin with, add on the general hardships of transition, supporting yourself etc., rude people who won't respect or acknowledge your identity, and it can get very taxing.
I felt like killing myself multiple times, but I held on, because I knew even though I wasn't where I wanted to be yet, I know I'll be there someday and I'll be very happy and proud for having soldiered through all the pain. You can't get to that happy place if you're dead. Trust me, most people who have transitioned have experienced what you are going through. Keep your head high darling!
