Depression is a mental health disorder characterized by persistent feelings of sadness, hopelessness, and a lack of interest or pleasure in activities that were once enjoyable. It can lead to significant disruptions in sleep, appetite, energy levels, and overall functioning. People with depression may experience difficulty concentrating, feelings of guilt or worthlessness, and even thoughts of self-harm or suicide. Depression can be caused by a combination of genetic, biological, environmental, and psychological factors. Treatment options include psychotherapy, medication, and lifestyle changes. Early recognition and intervention are crucial to managing depression and improving the individual’s quality of life.
