A mental institution is not always a good starting point, especially if they are committed involuntarily. It can actually make things worse as the experience of being committed involuntarily is often traumatic to the individual. Inpatient treatment is not always loving or validating, especially in environments where the inpatient treatment is for poor or homeless individuals. Homeless shelters aren’t always equipped for individuals suffering from schizophrenia, but homeless shelters are not really the loving and validating spaces someone who is mentally ill may need anyways. I know there are apparently programs that House the mentally ill in small apartments or with willing caretaker families That are paid for it.

I’m not saying “you are wrong and I have the answers”, merely that thmakes perception that anyone who talks to themselves needs inpatient and medication may not be necessarily true. They could just need some time in a safe place, while inpatient treatment can actually not be safe and incredibly traumatic.
