rejection

Social rejection occurs when an individual is deliberately excluded from a social relationship or social interaction. The topic includes interpersonal rejection (or peer rejection), romantic rejection, and familial estrangement. A person can be rejected or shunned by individuals or an entire group of people. Furthermore, rejection can be either active by bullying, teasing, or ridiculing, or passive by ignoring a person, or giving the "silent treatment". The experience of being rejected is subjective for the recipient, and it can be perceived when it is not actually present. The word "ostracism" is also commonly used to denote a process of social exclusion (in Ancient Greece, ostracism was a form of temporary banishment following a people's vote).
Although humans are social beings, some level of rejection is an inevitable part of life. Nevertheless, rejection can become a problem when it is prolonged or consistent, when the relationship is important, or when the individual is highly sensitive to rejection. Rejection by an entire group of people can have especially negative effects, particularly when it results in social isolation.
The experience of rejection can lead to a number of adverse psychological consequences such as loneliness, low self-esteem, aggression, and depression. It can also lead to feelings of insecurity and a heightened sensitivity to future rejection.
