Being sent to a residential facility means living temporarily in a supportive treatment setting while receiving structured mental health care. Adults may participate in individual and group therapy, psychiatric services, family sessions, skills work, and other evidence-based supports. Residential care offers more structure than outpatient treatment and can help stabilize complex psychiatric, trauma, substance use, or co-occurring conditions in a supervised environment.
