I can definitely see how T's response would trigger some serious feelings and I am sorry that you are struggling with this. It can definitely be read in a way that feels like you are being scolded but, if it is possible for you to step back from the emotions involved, it can also just be read as him calmly setting boundaries. The therapeutic relationship is a confusing mess sometimes. I think you have every right to ask for what you need. That being said, he also has the right to refuse. Who knows, maybe he has insecurities too that make him uncomfortable standing at the end of the appointment.... like maybe he sweats a lot and if he stood you would see his whole backside was soaking wet from sitting so long or there is a pool of sweat in his chair or something like that. Anyway, I really hope you are able to go in and reconnect with him and work this out. In the long run, does it really matter if he sits or stands at the end? I know you said that it was about something else, but you weren't sure what. Maybe spend the time from now until your next appointment focusing on that and not so much how he ends the appointment? Sometimes it helps me to try and figure out what other time in my life I felt similar feelings and work out from there.
