Frustration is an emotional response that occurs when a person feels blocked from achieving a goal or fulfilling a desire. It often arises from situations where expectations are not met, leading to feelings of annoyance or disappointment. Common triggers include obstacles, failures, or conflicts that prevent progress, whether in personal life, work, or relationships. This emotion can manifest physically and mentally, causing stress and tension. People may express frustration through various behaviors, such as complaining, withdrawing, or even acting out. Understanding and managing frustration is important for emotional well-being, as it can impact overall happiness and relationships with others, including family and friends.
