Rejection sensitive dysphoria (RSD) is extreme emotional sensitivity and pain triggered by the perception that a person has been rejected or criticized by important people in their life. It may also be triggered by a sense of falling short—failing to meet their own high standards or others’ expectations.
When this emotional response is externalized, it looks like an impressive, instantaneous rage at the person or situation responsible for causing the pain.
