Mood is the persistent state of emotion. It is something personally felt by the ‘feeler’ and usually is observable to others too. Some are positive mood states: happiness, excitement, exhilaration, exaltation, while others are characteristically negative ones like sadness, disappointment, gloom, frustration, despondency or depression; to name a few. Everyone goes through different emotions through their lifetime, over the years, months, weeks, sometimes even several times a day. A low mood is a problem and if there was an option, one rather not have to deal with it; yet it is a slice of life that one must devour. Life cannot be positive all the time. However, when a negative emotional state is persistent, and it causes longstanding trouble to the person feeling it, it qualifies as a disorder.
