Anxiety is a psychological and physiological state characterized by somatic, emotional, cognitive, and behavioral components.[2] The root meaning of the word anxiety is 'to vex or trouble'; in either the absence or presence of psychological stress, anxiety can create feelings of fear, worry, uneasiness and dread.[3]. Anxiety is considered to be a normal reaction to stress. It may help a person to deal with a difficult situation by prompting one to cope with it. When anxiety becomes excessive, it may fall under the classification of an anxiety disorder.[4] The intensity and reasoning behind anxiety determines whether it is considered a normal or abnormal reaction.[5]

Description

Anxiety is a generalized mood condition that can often occur without an identifiable triggering stimulus. As such, it is distinguished from fear, which is an emotional response to a perceived threat. Additionally, fear is related to the specific behaviors of escape and avoidance, whereas anxiety is related to situations perceived as uncontrollable or unavoidable.[6] An alternative view defines anxiety as "a future-oriented mood state in which one is ready or prepared to attempt to cope with upcoming negative events",[7] suggesting that it is a distinction between future vs. present dangers which divides anxiety and fear.
