I just came out to my mother!

I've been wanting to come out to my mother that I'm bigender for months, and today was the day. I asked her how she felt towards transgender people through e-mail, talking in person is too much for me when it comes to very personal things, or if there's a chance of things going bad. After I sent the e-mail, I began to have an anxiety attack and locked myself in the bathroom with my phone so i could se her reply.
After a few minutes she replied. Her reply was:

"I have no issue/problem/concern with trans-genders. If someone wants to be a boy, go be a boy. If you want to be a girl, be a girl. What matters most in life is that you're happy."

I was crying so much after reading this, but it was tears of relief and happiness. I knew my mom was basically opening the door fully for me to come out. So I just told her everything.

I told her when I found out, told her what bi-gender was, and told her the reason why I was scared of coming out. After that, we had a small heart-felt talk, and I told her she was the greatest mom.
And I started crying again when she said i was "the greatest daughter/son". A few minutes after I calmed down, I came out of the bathroom to hug my mother.

Sadly, I still havent told her that I wand to start binding or that I maybe want to get on testosterone. I don't want her to overload after telling her so much in one day, but I'm planning on telling her soon.
