Thank you all for your replies!
I don't really know what all the hesitation is about. I'm very reserved and put up walls to protect myself so this level of openness about the real me is really scary. T is not religious and I know in my head she would accept it and help me through it, but there is still that worry for some reason. I was never accepted for who I was growing up and didn't really have a voice, so it's just hard for me to be able to do this kind of thing. I think another part is knowing that this would mean discussing this with T and eventually coming out all together.
