Which of the following is a sign of anxiety disorders?

Excessive worrying is a hallmark symptom of anxiety disorders and is defined by persistent and uncontrollable concerns about various aspects of life, such as health, finances, or relationships. This constant state of worry can significantly impact a person's daily functioning and overall quality of life. Individuals with anxiety disorders often find it challenging to manage their worries, leading to increased levels of stress and heightened anxiety responses.

In contrast, complete emotional stability, increased social activities, and high self-esteem are not characteristic of anxiety disorders. Those coping with anxiety may experience emotional instability, social withdrawal, and a decrease in self-esteem, making excessive worrying the most relevant and indicative sign of an anxiety disorder.
