Hugs Gina,
I just do not understand why some people put so much effort and time hurting someone else. I wonder if she feels responsible for you being trans* or feel her reputation is being damaged. Whatever her issue is it is her issue and not yours. Perhaps with time she will realize the world does not revolve around her and she lost a wonderful daughter.
You have really made a move in the right direction and kept to your identity, congratulations.
