Answer:
b. poor social support; substance use
Explanation:
There are situations where mentally ill people are reneged on by the family and find no social support in any way, because of inappropriate behaviors stimulated by mental illness, such as outbreaks of violence, for example.
In this case, these people, having no support, are left homeless and end up living on the street. In this inhospitable environment, they end up using harmful substances in an abusive way, which worsens mental illness and results in an even greater lack of social support, preventing them from being welcomed.
