I had I think, a related issue. I moved, need a new dentist, called one, told them I wanted to take a sleeping pill because it helps me with my anxiety from previous painful dentist visits. They said they'd have their office manager call me back. He vehemently steered me to another dentist. It was ridiculous how much corp-speak he used to try to convince me it was in my best interest. They had a 5/5 rating. I assume it's because they reject anyone the think might lower it.
You're probably reading too much into that interaction. Look for a local sedation dentistry practice. They specialize in managing patients with anxiety. Regular dentists may not be set up to handle patients with major anxiety.
Asking someone to temporarily take on the responsibility of your medical wellbeing while admittedly being on psychotropics is a bit of an ask, isn't it?
