it looks like one of the reasons they're so strict about #ADHD diagnoses here is simply about capacity, according to this news story i'm reading:
the public mental healthcare system is completely overwhelmed. it doesn't have enough money and resources and must triage heavily.
some people get diagnosed by private healthcare providers and pay big sums for it, yet still get turned down for further assistance when they return to the public healthcare system afterwards. a diagnosis isn't enough. it must be a very serious case to be eligible for therapy.
this severe under-capacity explains a lot. that's why they offer so little help. best you can hope for is medications or welfare money.
