More than a bad mood, depression can make your whole life seem bleak and hopeless. It can feel like there’s no way out, plus you may feel too exhausted to care. For many sufferers, even getting out of bed in the morning feels as feasible as a trip to the moon. Left untreated, the condition can last for months or years, often getting worse. However, depression is highly treatable. Up to 80 percent of people who seek help for depression see their symptoms improve.
