Oh musinglizzy, I'm so sorry you are going through this again. It is understandable that it would take you back to when the boundary changes occurred with the other therapist, even if this sounds like a very different scenario. Of course those feelings would resurface for you, as I bet they were quite close to the surface anyway. I am also sorry that your therapists seem to be abusing the consent you gave them to communicate with each other. You should definitely retract it if you feel it is detrimental to your treatment.

I hope you can work things out with the somatic therapist, as it sounds like she has been helping you a lot up until this point.
