Mental Illness

A plain-language overview of what a mental illness actually is, and how common they are.

What it is

A mental illness is a diagnosable condition that significantly affects how someone thinks, feels, or behaves, and that causes real distress or difficulty functioning — not just an unusually hard week. Mental illnesses span a wide range, from anxiety and depression through to bipolar disorder and schizophrenia, each with its own patterns and treatments.

Good to know

Mental illness is far more common than most people assume — roughly one in five people will experience one in any given year, across every background, income level, and walk of life. It is not a character flaw or a personal weakness.

What helps

Most mental illnesses respond well to some combination of therapy, medication, peer support, and lifestyle factors, and many people who receive treatment go on to live full, stable lives. Treatment usually works better the earlier it starts, which is the main argument for not waiting.

When to seek help

If something is affecting your ability to function, work, or maintain relationships over a sustained period, that's worth a conversation with a doctor or counsellor, regardless of whether you're sure it qualifies as an “illness.”
