Fixated,
Can you try not to think of t as someone who is just doing her job?
try to think of her as somebody who does genuinely care? I really can't beleive she told you that, it was cruel and its no wonder you feel like this.
Of course the reality is that, she is somebody doing a job but I would hope that she does it because she enjoys it and because she cares.
Lets look at this from a different perspective, has t ever shown you that she does not care?
Have you ever felt that during your session she showed you that she didn't care? If she did then it is a fact but I really don't think your t means that, I hope she was having a bad day that day or perhaps she was just holding good boundaries by telling you this, maybe she tells all of her patients this. I don't see how it could be very therapuetic but maybe she is afraid to admit she cares. It is easier for her to pretend she doesn't.
I don't know what her reasons are but it is up to you if you believe it to be true and if you do I think it will hinder your progress. I personally could not work with a t that said that.
