Persecution Complex is a psychological term used to describe an individual's irrational fear of being persecuted or discriminated against. It is closely related to PARANOIA, which is defined as an irrational fear of being persecuted or harmed by others. People with a persecution complex often feel that they are being targeted or singled out for mistreatment, even when there is no evidence to support this belief. This can lead to feelings of anxiety, depression, and isolation.
