Hey honey, I don't have much to say, but here I go. Two of the few that I came out are my parents, and I have been reject pretty hard by them. They kind of prefer to have never had children than have a mtf daughter. If I let them, they will force me to live as a normal man, because they think that I'm ruining my life and want to prevent me to do so (In my mother's mind, if try to be a girl, I'll never find a job, a girlfriend, never be passable or respect by people and she fears it, as I do). I know that they love me, and I think that you know in you heart if you family loves you, for me, love is the start of acceptation. May be you mother is worried about you, that's why she seems to be so reluctant, may be she wants to support her growing daughter but has the same fears that my mom's have. Try to take it easy with her, it's not easy to her too.
I know that feeling when people seems to just tolerate us, it's kind of disgusting, but you can keep giving a second chance, may be someday It will change. People are not prepared for change, to accept the different, they need time to it, we need to learn this, and give that time.
