I think your situation is very similar to what I'm going through with my therapist making a comment about us having a business relationship. It hurts because it bursts the bubble on the fantasy we create where our therapists are more, almost like my parents left a gaping hole in me that I am looking for someone to fill and I think oh, the therapist fits nicely there... problem is no one can fix that hole. I don't know how the hole get's fixed, or maybe we just move on and it gets overlooked, I just don't know...

At the end of the day it's not like your therapist has said anything mean or untrue, she cant be your mom, and she cares about you. Really she's doing the best you could ask her to do. The wound is from something else. It just sucks.
