Sadness is a perfectly normal reaction to life’s struggles, setbacks, and disappointments. Many people use the word “depression” to explain these kinds of feelings, but the symptoms of depression are much more than just sadness. Depression is the overwhelming feeling of sadness when everything in your life seems to be going right. However, some depressed people don’t feel sad at all, they may feel lifeless, empty, and apathetic, or some may even feel angry, aggressive, and restless. Whatever the symptoms, depression is different from normal or ecological sadness in that it takes over your daily life, interfering with your ability to work, study, eat, sleep, and have fun. The feelings of helplessness, hopelessness, and worthlessness are intense and unrelenting, with little, if any, relief.
