We should not force someone to choose between mental health treatment and God. God and church congregations, plus mental health treatment can help tremendously those who are suffering from the debilitating effects of schizophrenia, bipolar disorder, major depression and anxieties/phobias. Untreated mental illnesses cost people their jobs and interpersonal relationships.
I come from a large extended family whose members have experienced a great deal of mental illness. I also come from a family with a deep devotion to God.
Over the years I have seen churches explicitly and implicitly tell their congregations that if they were "right with God" then they would have no need for psychotropic medication and counseling. I have watched as sick relatives have worked hard to regain their health, only to have it slip away from them after some well-meaning person at church convinced them to throw away their medication.
