Sorry to any of you hoping for good news:
My mom sat down in the cafe and she was visibly shaking. She asked in an abrupt tone "Do you have answers for my questions?". So I went in to my gastrointestinal doctor saying everything is okay and that he doesn't have a problem with my transition. That may have helped my Aunt, but it didn't help my mom. She tried to blame herself "What did we do to you ash a child to cause this?" and I answered with how being trans is just who I am, it's not anyones fault. I don't think she bought it. I also don't think she believed me when I said that estrogen is used to repair bone loss and not to encourage it.
She also asked about my future - would I feel comfortable living a lie and not having any history? I figured I would be honest here that no, I'm not comfortable living a lie. That's why I'm transitioning in the first place, and I'll be more than willing to be open with my friends, family, and SO (since it's important to be honest with him or her).
Somewhere in there she commented on how much of a mess she was. And that she's thought about killing me enough to have my dad hide their gun from her. I'm really, really, really scared right now and I see it taking a long time for me to ever feel comfortable in their house again. Apparently even my dad was worried about her "let's go on a nature trail. alone." plan. Apparently she actually had thought about taking me out there and then leaving my body for the squirrels.
Other notes - she said I'm being selfish, and that I have to think about how others react. She doesn't care that I feel better about myself now because I always seemed happy around them (of course, during those times she just mentioned my thoughts were "hold the smile and nobody will have to know that anything is wrong"). She thinks my brother has taken it poorly because he didn't want to talk about me during their California trip. She prays to her God every day asking for a way to stop caring about me so she can let me go. She said "no" to therapy today because she doesn't want somebody trying to change her mind.
How am I doing after this? I'm terrified. It will be a long, long time before I ever feel comfortable setting foot in their house now that I know they have a gun and that she's thought about using it on me. Just thinking about it has me in tears right now. I don't see much hope for a good relationship after this.
