Mental illness occurs because of many factors working together, including genetic inheritence, family environment, cultural background, life stresses and events, and importantly, physical illness. Some forms of mental illness are caused by chemical imbalances in the brain - not by bad parenting. Many people experience only one episode of mental illness in their lives and afterwards suffer no lasting ill effects. Others may have episodes recurring at intervals throughout their lives. Some people live with chronic mental illness.
All cases are different.
