Resentment is a complex emotional response that arises when an individual feels wronged or treated unfairly. It often involves feelings of anger, bitterness, and disappointment, typically directed towards a person or situation that is perceived as unjust. This emotion can stem from various experiences, such as betrayal, discrimination, or unmet expectations. Over time, unresolved resentment can lead to negative consequences, including stress and strained relationships. It may also manifest in behaviors like withdrawal or passive-aggressiveness. Addressing and processing feelings of resentment is important for emotional well-being and can involve communication, forgiveness, or seeking professional help.
