emotion referring to the thoughts and feelings of insecurity, fear, and envy over relative lack of possessions, status or something of great personal value
Jealousy or envy is a feeling (or emotion) people get when they want what others have. This is a negative feeling. When someone is jealous of someone else, they usually dislike the other person. These particular emotions are usually caused by a person having a certain object or quality which you desire but can not obtain. Jealousy is caused by lacking of self confidence and judging your abilities. Jealousy is not reasonable rationally.
