The incident was bad enough, then they added insult to injury by telling you the reason the patient needed to get in. That must have felt invalidating to you and would really infuriate me. In my opinion, it is a totally unprofessional way to handle the situation. I am curious as to why your T "admitted" to it being her fault, as if it matters whose fault it is. She seems to be clueless. Why have you lost your appointment before if you want to share. I would definitely let your T know how you feel and why. No, admitting fault isn't the same as apologizing to you. I would also ask if you can expect consistency in the future. For me, my T's consistency is a huge part of my therapy. Let us know how it goes.
