Wow thanks everyone for the replies! I'm really feeling a boost from talking with you all.
@Malachite This is almost the same thing that my Mom said to me as I also come from a rougher childhood. Thanks, I hope my mom comes around too, maybe it'll be like Jessica said and they'll miss us enough to come around at least in some respect.
@Jon I agree. It shouldn't be like this at all. What's funny is they think they're trying to help us when really all it does is hurt us. You're right, family isn't always blood related, I need to keep that in mind.
@Jay. It sounds like religion can really make things difficult for a lot of us. I'm glad your mom came around, I hope I'll be able to say the same thing someday. I definitely believe this is a birth defect, but I wonder if she'll ever see it that way. Maybe I just need to accept this in her and not take it so personally.
@FlightyBrood It's good to know that this is a pretty common thing that happens. It's comforting in a way really, especially knowing that they all did come around. My mom would never go to a PFLAG meeting

It'd be pretty cool if she did, though, or any of my family for that matter.
Again thanks everyone. You guys are really helping me in this hard situation. It makes a difference being able to talk to people about this who really get it.
