Which psychological condition is characterized by feelings of sadness, melancholy, or despair?

Depression is a psychological condition marked by pervasive feelings of sadness, melancholy, or despair. Individuals experiencing depression may also have a loss of interest in activities they once enjoyed, disturbances in sleep, appetite changes, and a general feeling of hopelessness. This emotional state can significantly affect daily functioning and quality of life.

In contrast to other conditions like anxiety, which is characterized by excessive worry or fear, or stress, which is a response to external pressures, depression primarily revolves around internal feelings of deep sadness. Euphoria, on the other hand, refers to a state of intense happiness or well-being, which is the opposite of what is experienced in depression. Understanding the nuances of these conditions helps in identifying them accurately and seeking appropriate support and treatment.
