Sadness in mood is a normal reaction to life’s struggles, setbacks and disappointments. Many people use the word “Depression” to explain these kinds of feelings, but depression is much more than just sadness. Some people describe depression as “living in a black hole” or having a feeling of impending doom. However, some depressed people don't feel sad at all—they may feel lifeless, empty and apathetic or some patients may even feel, irritable and restless

Whatever the symptoms, depression is different from normal sadness in that it engulfs your day-to-day life, interfering with your ability to work, study, eat, sleep, and have fun. The feelings of helplessness, hopelessness, and worthlessness are so intense that it hampers day to day activities.
