Sometimes, though, mental health issues cause people to behave badly and cause harm to others, in ways that are not cute or sympathetic or easily understandable. An old friend with a personality disorder once wanted to write about this, on Mental Health Awareness Day: that we’re all keen to be Aware of Mental Health when it means someone being anxious or unhappy. But when it’s about psychotic episodes — or even less sympathetic disorders, such as psychopathy or narcissistic personality disorder — we’re less keen.
