Your feeling hurt is appropriate and valid in this kind of situation.

Your T screwed up by not maintaining professional boundary from the beginning by giving you extra time after your double session. This way she has set a routine you have gotten used to and changing this routine now understandably makes you unstable, and, if you are in crisis, it only exacerbates it. As a therapist, she has to understand the importance of consistency when working with highly traumatized people. If she had to make changes for whatever reason, this had to be run by you, discussed with you in advance, not just imposed on you like that. So, yeah, I am sorry, but that's a screw up on her part. Sorry you are hurting. Your pain is completely understandable.
