If it were me and I felt bullied by my therapist, I'd try talking it out for one, maybe two sessions. But if I still felt unheard, I'd walk.
Even if the psychiatrist was helpful to you in the past, you might have gotten to a point where he isn't helping any more.
I had a therapist I was seeing for over 20 years, and she was quite helpful for most of that time. However, I reached a point where it was less about dealing with specific neuroses and the like and was -- or would have been -- more about me finding out who I was. She wasn't all that good at validating my perceptions when they differed from hers, which meant I was spending my time handling her reactions to what I was feeling instead of trying to figure out what I was feeling and what it said about who I was. So when I left, it was as much with relief as with sadness. (We never got to my gender issues, I seriously doubt she could have dealt with my being trans.)
IMHO, it's really important to feel your therapist is on your "team you." You should be able to discuss your relationship with your therapist
with the therapist. If you fear he won't accept it or will gaslight you, there's no theraputic relationship left.
Also, I can't help thinking: if you have to come
here to figure out how to deal with
him, maybe you should be paying us instead of him.

(<-- that's a joke, BTW.)
