📖What is Depression?
Depression is a common but serious mood disorder characterized by persistent feelings of sadness, hopelessness, and loss of interest in activities that were once enjoyable, lasting for at least two weeks and significantly impairing daily functioning. It affects how a person thinks, feels, and handles everyday activities such as sleeping, eating, and working, and can range from mild and manageable to severe and disabling. Depression arises from a complex interplay of biological, psychological, and social factors rather than simple sadness or a personal weakness. It is highly treatable, though it often goes undiagnosed and untreated due to stigma and lack of awareness.
