Most of us would not think of someone with a broken leg as incompetent or lazy. Nor should we about someone living with a mental illness. Mental health is health.
Additionally, it is often assumed that someone living with a mental illness might be dangerous or unpredictable. This is despite the fact that people with mental illness are far more likely to be victims of violence rather than the perpetrators.
We can help destigmatize mental illness by educating ourselves and challenging our conscious and unconscious biases.
