Mental health is just as essential as physical health. In Australia, where workplace pressures and personal challenges are common, understanding mental illness is crucial, especially for adults aged 20 to 50 entering or navigating the workforce. The guide explores what mental illness is, its causes, symptoms, types, treatments, and strategies for prevention and support.
What is Mental Illness?
Mental illness refers to a wide range of conditions that affect how we think, feel, and behave. Unlike everyday emotional ups and downs, mental illnesses are diagnosable disorders that can significantly disrupt daily life.
Mental Health vs Mental Illness
- Mental health is a state of emotional, psychological, and social well-being.
- Mental illness refers to conditions like depression, anxiety, and schizophrenia that interfere with functioning.
For example, feeling nervous before a presentation is normal (mental health), while persistent, overwhelming anxiety that hinders daily life may indicate an anxiety disorder (mental illness).
