Fear

Fear  is a distressing negative sensation induced by a perceived threat. It is a basic survival mechanism occurring in response to a specific stimulus, such as pain or the threat of danger. This set also includes such emotions as joy, sadness, and anger. Fear should be distinguished from the related emotional state of anxiety, which typically occurs without any external threat. Additionally, fear is related to the specific behaviors of escape and avoidance, whereas anxiety is the result of threats which are perceived to be uncontrollable or unavoidable. Worth noting is that fear almost always relates to future events, such as worsening of a situation, or continuation of a situation that is unacceptable. Fear could also be an instant reaction to something presently happening.

Fear is a vital response to physical and emotional danger—if we couldn't feel it, we couldn't protect ourselves from legitimate threats. But often we fear situations that are in no way life-or-death, and thus hang back for no good reason. Traumas or bad experiences can trigger a fear response within us that is hard to quell. Yet exposing ourselves to our personal demons is the best way to move past them.
