    Loneliness is an unpleasant feeling in which a person experiences a strong sense of being alone resulting from low levels of social contact and relationships．

There are two types of loneliness： emotional loneliness and social loneliness． Emotional loneliness is concerned with the relationship between parents and their children． When children are separated from their parents， they show separation pain， such as crying and trying to search for their parents． Therefore， emotional loneliness is caused by a lack of a person that one is normally emotionally attached to， such as a parent． Social loneliness， on the other hand， is the loneliness one experiences through a lack of a wide social network． One does not feel that he or she is a member of his or her community， and one does not have friends that he or she can rely on in times of pain．

One way of thinking about loneliness is from the difference between one's desired and one's achieved levels of social interactions， while being alone is simply a lack of contact with people． Loneliness is therefore a subjective experience； if people think they are lonely， then they are lonely． People can be lonely when they are alone， or in the crowd． What makes people lonely is the fact that they want more social interaction． People can be in a party and feel lonely because they don't get to talk to enough people． On the other hand， one can be alone and not feel lonely， even though there is no one around． That person is not lonely because he or she has no desire for social interaction at that time．
