How ignorant is the US government of mental health conditions?

I think that pretty much covers it.

You have the bullying at schools which leads to suicides, you have the mass slaughters at premiere film releases and oh yes, schools, these people clearly had issues, and in many cases – especially with bullying – the issues were known but clearly not enough was done to rectify the situation….and worse still, nothing reasonable seems to be happening to rectify the problem (which it is, a problem).
So how ignorant are the US government of people with mental health conditions, and what exactly are they doing about it?
