I think that this is a poor target. How do you set out directly targeting mental health? What are the biggest causes of mental health issues?
https://www.cdc.gov/mentalhealth/learn/index.htm
CDC lists causes such as childhood trauma, trauma from medical issues, biological factors, alcohol or drugs, and loneliness or isolation.
How do you set out to tackle loneliness or isolation? How do you help prevent alcohol or drug addiction? What are the reasons that people become addicted to drugs or alcohol?
> Use and misuse of alcohol, nicotine, and illicit drugs, and misuse of prescription drugs cost Americans more than $700 billion a year in increased health care costs, crime, and lost productivity.

> Some must cope with the early loss of a parent, violence, or sexual abuse. While not everyone who faces these stresses develops a mood disorder — in fact, most do not — stress plays an important role in depression.

This is a big interconnected problem. My point is that just giving directly to mental health resources rings hollow. A tougher holistic approach needs to examine why American society just plain sucks for so many people. Why do people want to kill themselves or others? Why does life suck so much for so many? We have a rotten system and drug addiction/gun violence/suicide are symptoms and not causes.
My 2 rambling cents.
