I saw a PBS documentary. It had 3rd world countries.
In some places in Africa a child who suffers mental illness is locked in a small cell in the back yard. And sometimes they can't stand up all the way. They need to go to the bathroom in the shed. Sometimes for 15 years.
Then it had some stories about some rural areas in India. The mentally ill were locked in a bedroom. Same thing. No bathroom in there. No medical attention. No therapy. No meds.
There are people suffering the world over.
