Languishing is the neglected middle child of mental health. It’s the void between depression and flourishing — the absence of well-being. You don’t have symptoms of mental illness, but you’re not the picture of mental health either. You’re not functioning at full capacity. Languishing dulls your motivation, disrupts your ability to focus, and triples the odds that you’ll cut back on work. It appears to be more common than major depression — and in some ways it may be a bigger risk factor for mental illness.
