Which of the following best defines anxiety?

Anxiety is best defined as a state of feeling apprehensive and fearful, as it encompasses the emotional experience characterized by feelings of worry, nervousness, or fear about potential outcomes or events. It often includes physical symptoms such as increased heart rate, sweating, and a sense of impending danger or doom. This emotional state can vary in intensity and may be triggered by various factors, including stressors or uncertainties in life.

Understanding anxiety is crucial for recognizing its impact on individuals, as it can affect their daily functioning and mental health. The other definitions do not accurately capture the essence of anxiety; for instance, confusion and emotional stability diverge from the feelings specifically associated with anxiety, while relaxed concentration suggests a state of calmness rather than apprehension.
