Alright, so I've finally accepted that I'm a transman, and have been coming out little by little to select friends and family (previously only a small handful of close friends and my husband knew about it). I want to start transitioning, and obviously some effects will be noticeable after a while. So I decided to come out to everyone I know via Facebook. I'm a little concerned though. I'm not sure how some friends and family will handle it. I have an uber-religious dad who thinks LGBT people are societal dregs and they are better off dead. I know I'm going to loose him, but at the same time it seems I already have. Ever since his wife and him got married over 11 years ago, it's been more about her kids than me, so I've been feeling slowly pushed out of the family (it should also be noted he's my "adoptive" father. My bio dad wasn't around much after the divorce when I was 9 or 10, so as a friend of the family he stepped in and made me his daughter.) The feeling was made clear when I went home last and I seemed more like a burdensome irritant than daughter.
I'm not sure how to word any of this, or how to tell people I know won't accept it. I'm also terrified of becoming some sort of joke amongst some family members. I don't like the idea of becoming the object of mass ridicule and being ostracized. My lesbian aunt already won't talk to me about it, and I fear pressing the issue lest I loose my connection with my nephews that I love dearly. My mom keeps trying to convince me I'm not a transman and that I probably have "underlying issues making me think it's what I want". She won't believe it until a therapist agrees, and even then she said she doesn't know if she can ever come to a time when she can accept it. The only one in the close family so far to accept me as I am is my bisexual sister. She has also been discriminated against by our aunt for being bi, so she knows what it's like.
I'm just so unsure. Some days I'm ready for anything, some I'm petrified. What should I do? Any advice?
