What is characterized by fear, apprehension, and a sense of impending danger often accompanied by physical symptoms?

Understanding the characteristics of anxiety is essential as it encompasses feelings of fear, apprehension, and an overwhelming sense of impending danger. Anxiety manifests both psychologically and physically, often resulting in symptoms such as increased heart rate, sweating, trembling, and muscle tension.

This emotional and physical response is a normal reaction to stress, but when anxiety becomes excessive or persistent, it may interfere with daily activities. It is crucial to distinguish anxiety from other mental health conditions. For instance, stress refers to a response to a specific external trigger, while depression involves prolonged feelings of sadness and disinterest. Panic disorder, while it also includes intense fear and physical symptoms, typically presents in episodes of sudden panic rather than the continuous feelings characteristic of general anxiety.

Thus, the focus on the pervasive nature of fear and the sense of danger that accompanies anxiety makes it the most fitting answer in this context.
