In the US normally you talk to a therapist (not a doctor) or psychologist (not a medical doctor) about your depression at length, and then if you're deemed sufficiently depressed you get a short consult with a psychiatrist (finally a doctor) to prescribe medication. This is when you would theoretically finally be able to bring up shrooms, and your psychiatrist will laugh at you, write an Rx for an SSRI, and you'll see him next year when the Rx expires
I'm not sure how it is in most countries but I'd expect the biggest difference is that it will cost you money in the US, but I've read many many horror stories about people waiting many months to have only a short chat with a physician from other countries. The lack of time available to spend taking to physicians seems to be a problem in other places too
my point is that consulting a doctor with random questions isn't a simple, casual thing people can easily do in most places. in most places you have to plan ahead and either wait a long time for an appointment, and/or there is a cost barrier.
if you have examples of countries where people are able to get to know their doctors on a personal level and can afford in time and money to talk to their physicians for more than a few minutes per year, please link them below
