While it’s normal to experience various moods and emotions due to different situations and circumstances, major or clinical depression occurs when you frequently feel sad, hopeless, or helpless for no apparent reason. You may experience low moods and lose interest in activities you used to enjoy.
Other psychological symptoms of depression include feeling irritable, unmotivated, and indecisive. Physical symptoms include low energy, sleep issues, and digestive concerns.
To receive a clinical depression diagnosis, you must exhibit symptoms of depression for at least 2 weeks.
