Perth / Western Australia

Well diagnosis comes before hospitalisation. The receptiveness and recognition has increased throughout the whole population, led by our health systems.

That recognition 'Led by our health systems' is actually very important in your other point about the western world moving in unison on this. Sure there is a geographical distance, but due to the shared histories, language, and dominance of the US on the open web the 'western world', as its called, is more in unison than we are with other potential country groupings, say in Aus and NZ's case the Asia Pacific group of nations.

Take this general scenario of closeness, and magnify it even more for the western world's medical community, due to shared medical and ancillary companys, journals in english, similar medical systems with transferrable skillsets, and the medical schooling.

I find its not hard at all to believe suchxa rapid and in unison rise.

I do have an addendum, i believe there might be some over diagnosis occuring, through no ones fault. But the sudden acceptance, i think, is leading people to overly assess their own and warranted unhappiness and externalise these feelings as more acute medical issues than they need to be, of course that might be creating a treatment spiral with some people, which is a whole thing in itself!

So i guess i don't disagree with your point really, it probably is due to more factors, but i think the acceptance and actually diagnosing people's mental health rather than ignoring it is doing the heavy lifting.
