Just because someone "knows" you, doesn't mean they can read your mind. What she probably means is she gets your thinking about your past, your mother, your abuse, etc. That doesn't mean she knows verbatim what is going on in your head.

I "know" my husband very well. I understand the way he thinks and generally where that comes from. That doesn't mean I know exactly what he is thinking at any moment.

It isn't that she is unwilling to help you do this. In fact, she's been working to help you do this for years. But the bottom line is that it is us who have to ultimately make the discoveries about ourselves and work through whatever our issues are. The whole world out there, including our T's, can "know" what our issues are and tell us what they are and what we should do until they are blue in the face, but until WE understand those things by making those discoveries about ourselves for ourselves, they are just spinning words.

She probably has no problem handling big emotions. She's waiting for you to put them out there, and once you do, she will walk you through them. A T can't pull them out of us until we are ready to let them do so, and some of us are hanging onto and stuffing down those emotions and experiences for dear life.
