Sadness is a temporary emotional state, often tied to specific events. Depression, however, is a clinical condition that persists for weeks or longer, affecting mood, thoughts, and physical health. People with depression may experience persistent low mood, loss of interest in activities, changes in appetite or sleep, fatigue, and feelings of hopelessness. It’s not simply "feeling sad"—it's a serious condition that requires understanding and treatment. If you or someone you know may be struggling, compassionate care is available.
