Major Depressive Disorder (MDD) is a serious mental health condition characterized by persistent feelings of sadness, hopelessness, and a lack of interest or pleasure in daily activities. Unlike temporary mood fluctuations, MDD affects how a person thinks, feels, and functions in everyday life, often leading to difficulties in work, relationships, and overall well-being. Symptoms may include fatigue, changes in sleep or appetite, difficulty concentrating, and thoughts of self-harm.
