Jealousy
Jealousy can be understood as an overwhelming feeling of insecurity about a potential loss or about perceived inequity in distribution of resources. The term has also been used for the purpose of describing a feeling that is associated with being possessive of another person, who might be a partner, closely associated relatives or a friend. It is a common emotion and most people have experienced jealousy from time to time, but when the magnitude of this emotion is quite high, it can greatly interfere with daily activities of life.
Jealousy is often interchangeably used with envy, however the two are distinct emotions. While jealousy is understood as a fear that another person might take away something that is priceless or important to a person or something he or she consider to be their, while envy can be understood as the desire for possessing something that belongs to someone else.
