Expecting medical institutions, taken as an entity, to prioritize the well-being of their patients is a fool's errand. I want to be very clear that I don't believe this about any individual doctors I've met. But there are a lot of doctors in my family, I've had minor to moderate brushes with the medical system, and I have immediate family that's significantly and chronically ill, and all those experiences and conversations have exposed me to the combination of a poisonous culture, institutional rot, insane legal restrictions, and doctors' (somewhat understandable) anti-patient biases adding up to a system that really doesn't give that much of a shit about your well-being if you don't fit into a clean box. Psychiatric issues in particular almost _never_ fit into a clean box, and the medical establishment is somewhere between criminally incompetent, negligent, and malicious when it comes to psychiatric issues.
Now despite all that acid cynicism, I'm not actually suggesting that you fully refrain from medical or psychiatric treatment. It's just not a system that's amenable to the kind of blind faith and surrendered autonomy that you describe, especially in the case like psychedelics where they've aggressively abdicated their responsibility for half a century.
