"Jealousy is an often overwhelming feeling of insecurity about a potential loss or inequity in distribution of resources. The term is also used to describe a feeling associated with being possessive of another person, such as a partner or friend. Most people experience jealousy from time to time, but extreme jealousy can greatly interfere with daily life. People who find that jealousy interferes with their life may consider speaking with a therapist to better understand what is causing this emotion."
