Defining depression and its various forms is essential in recognizing the diverse ways it can manifest in individuals' lives. Depression is more than just feeling sad; it is a persistent state of emotional and psychological distress that can significantly impair one's ability to function and enjoy life. It encompasses a range of symptoms, including feelings of hopelessness, loss of interest in activities once enjoyed, changes in appetite and sleep patterns, and a pervasive sense of worthlessness. By understanding the complexities of depression, we can better identify its symptoms and intervene effectively.
