I hope she only chose the wrong words to express what she meant.
In a way I think I understand what she means though. She probably wants you to be the way people are when they fall in love and fully start to trust one person, they feel safe enough to share everything, to be fully themselves, ...
I guess that's what your T means. And as you're quite sure that she would never say this in an inappropriate way... I hope this is what it's about.
But I don't know whether we can 'force' this. I mean, you fall in love with someone or you don't, you feel comfortable enough to share everything with someone or you don't...

I hope you ever get the feeling of being safe with your T, so you can talk about all the things you have to talk about in order for you to heal and get better.
