I agree with Chaotic. The only person who needs to be happy with who they are is you. It's beyond hard when someone you thought you could trust and lean on for support is basically ignoring you and treating you with utter rudeness and overall giving you the cold shoulder.

I'm not going to say that this will resolve with time, because I don't know your parents, but like Chaotic said, let's not think about that for now. Focus on you, and being happy with yourself. That includes making yourself happy with your outer appearance and finding inner peace.

Keep in mind that, as much as it's a change for you to come out to your parents about the gender you associate with and the transition you'll undertake to become the man you've always felt you were, this is also a huge change for your parents. They are obviously not open to the idea that gender is fluid rather than static and obviously feeling alarmed and scared that their "daughter" is now fully opening up to them as identifying as male. I'm not siding with them, far from it. Just pointing out that they are going through just about as much as you are right now.
