Loneliness

Loneliness is an unpleasant feeling in which a person experiences a strong sense of emptiness and solitude resulting from inadequate levels of social relationships. However, it is a subjective experience.[1] Loneliness has also been described as social pain - a psychological mechanism meant to alert an individual of undesired isolation and motivate her/him to seek social connections. Emotion is the complex psychophysiological experience of an individual's state of mind as interacting with biochemical (internal) and environmental (external) influences. In humans, emotion fundamentally involves "physiological arousal, expressive behaviors, and conscious experience."[1] Emotion is associated with mood, temperament, personality and disposition, and motivation. Motivations direct and energize behavior, while emotions provide the affective component to motivation, positive or negative.
