That would make me really sad, especially since he said he'd "discuss" it with you, but then just laid down the law instead.
I had a few experiences like that with my T and it was a big trigger for me. I started to respond to her like she was a controlling, all-powerful figure. In other words, I threw a tantrum and railed against her, telling her that she didn't give me any choice in it... instead of talking through it like an adult and an equal, who expected to be heard. I tend to get better results when I can stay more calm, express my feelings, and expect T to be reasonable with me.
I suggest you bring it up calmly and in an adult manner with your T, and ask for his reasoning. If you feel like he might be willing to negotiate and work with you, maybe you can ask him to reconsider? Maybe he wouldn't. Unfortunately that's a hazard of dealing with other people: sometimes they can't give or be what we want. And that's disappointing. & it's all the more upsetting when you have a history of not getting your most basic needs met. (I don't know your history of course)
Best of luck to you
