Art, I'm of two minds about your situation.

On the one hand, I know for myself that when I feel extraordinarily emotional, I've been triggered. That does not mean that the person who did the triggering was right--in this case, I think your therapist was really insensitive, considering the context of the discussion--but it might mean that you feel the same way, or fear there is truth in it, a kind of rejection of you and your worth. And that last part is worth looking at, because that's what follows you wherever you go. Again, it doesn't mean you don't have a right to be angry with your therapist, just that it could also be pointing to something deeper.

The other thing is that there is a bigger context here, which is that you went in wanting to discuss your relationship and wanting to matter to her beyond being a client (sorry if I got that wrong), and her comments were clobbering during a time you made yourself vulnerable. She messed up.

Bottom line: You don't owe her anything. Not a session on the 7th or anytime she suggests. This is your path and part of it is finding your own way, and that could mean some coming and going and breaks to sort things out.

I wish you the best in this. I hope you can see all the good that's coming out of defining yourself and your value.
