Mental health seems to be an issue not many govt want to deal with. The system in nz is scary. There is no room to help new patients and no resources to deal with everybody they have already.
When they closed most of the mental institutions they screwed up majorly! its left to families to care for people but very little help or education for those people.

Add to that drug related mental health problems...

Not all kids fall into a category. My ds1 is a special boy and without caring mature teachers at school he could be left in the sidelines.
