Depression is often described as feeling unhappy, sad, blue, miserable, or down in the dumps.
Many people feel down or fatigued sometimes in their lives, but generally for short periods. When these feelings persist and the grey fog that seems to permeate your brain does not lift, you may be struggling with clinical depression. Many feelings are incorporated in the lack of motivation and the desire for isolation. Frustration, anger, loss, sadness, hopelessness, worthlessness and even guilt can accompany the feeling of being depressed.
