Hugs, Scarlet. I'm sorry it was such a difficult session. I wonder if you do need a break--even just a week or two--to allow yourself to get out of the emotional mind? It sounds like you're stuck in the pattern with her--spinning, as she called it.
It also seems like she's putting the blame on you, wondering why you can't integrate the parts of her. Hm...I'm thinking of what she said with the spinning with you. Maybe that's part of the issue? You need her to be steady ground, something solid and unmoving to hold onto, but she's in there with you also spinning. Maybe she's also in her emotional mind?
