Thank you all so much for your quick responses. Particularly, I must thank Ericka... not because other responses weren't good, but because yours, I'd love to have my mother read. That's exactly the sort of thing I've tried to tell my parents, but they refuse to believe I know what I'm talking about.
I had a long talk with my mom tonight on this very subject. She says that her primary concern is my "relationship with God." I AM a Christian, though my beliefs are not exactly those of my parents... I don't attend church, but I fully believe that Jesus died for my sins, and try to practice the morality and kindness that he taught. However, I have time after time assured my parents that my relationship with god is absolutely fine, and that that is not the problem... the problem is that I would like to be accepted for who I am.
I made a mistake, apparently, when first coming out to my mom... I told her I thought god made a mistake, that I should have been born male. Tonight, even prior to reading any of your responses, I told her I believed I was born this way for a reason, because it has made me a far stronger person. I told her I would be glad to talk to her pastor, a therapist, or anyone she'd like, if she truly thinks I'm wrong in my thinking. She did not respond... only called me by my birth name and insisted that I had been convinced by other people that I'm trans.
I will keep trying. Being confronted by my parents' ignorance daily, however, is really hard on me. I am in a place now, the place where I went through high school and lived on and off for 8 years, where I don't feel like myself at all. People here know me as a girl, as my birth name, and none of them as yet will even begin to accept me as Sebastien. It's difficult. But it feels very good to know that there are people here who care.
