We all feel blue, unmotivated, melancholy or lethargic sometimes, but clinical depression is more than just experiencing temporary feelings of sadness. It is a serious condition that affects your mind and body. It impacts all aspects of your everyday life including eating, sleeping, working, relationships, and your self-esteem. If you are clinically depressed you cannot simply will yourself to feel better. If you do not receive appropriate treatment your symptoms can continue for weeks, months, even years. It is extremely important to treat depression as soon as possible as it may result in deadly situations (e.g. suicide).
