i believe you too... i am sorry that you are feeling that way.
i'll listen

. i don't know if this could be a possibility, but what if she hasn't brought it up in detail because you haven't brought it up in detail? i mean, you ask her if she believes you but sometimes we as patients have this body language... our tone changes or we cross our arms... maybe she doesn't want to bring it up because she doesn't know if you are ready to?
if that is just all a pile of rubbish then maybe it might be something like, this is HUGE to you (and would be to EVERYONE in your situation). you haven't trusted anyone with this and then you open up to someone who is supposed to accept and believe everything you say, you feel invalidated because the response expected from that kind of disclosure wasn't experienced... sometimes when a lot of emotion and trust is on the line, we don't give ourselves or our trustees credit because we are afraid of what they will think of us.
or, at the end of the day, your T can be acting like an as$hole. it happens.
please keep us updated! i want to know how everything is going
