There are two types of frustration; internal and external . Internal frustration may arise from challenges in fulfilling personal goals, desires, instinctual drives and needs, or dealing with perceived deficiencies, such as a lack of confidence or fear of social situations . Conflict, such as when one has competing goals that interfere with one another, can also be an internal source of frustration and can create cognitive dissonance . External causes of frustration involve conditions outside an individual's control, such as a physical roadblock, a difficult task, or the perception of wasting time . There are multiple ways individuals cope with frustration such as passive--aggressive behavior, anger, or violence, although frustration may also propel positive processes via enhanced effort and strive . This broad range of potential outcomes makes it difficult to identify the original cause (s) of frustration, as the responses may be indirect . However, a more direct and common response is a propensity towards aggression . </P> <P> Frustration originates from feelings of uncertainty and insecurity which stems from a sense of inability to fulfill needs . If the needs of an individual are blocked, uneasiness and frustration are more likely to occur . When these needs are constantly ignored or unsatisfied, anger, depression, loss of self - confidence, annoyance, aggression, and sometimes violence are likely to follow . Needs can be blocked two different ways; internally and externally . Internal blocking happens within an individual's mind, either through lack of ability, confidence, conflicting goals and desires, and / or fears . External blocking happens to an individual outside their control such as physical roadblocks, difficult tasks, or perceived waste of time . </P>
