Which of the following is a common symptom of anxiety disorders?

Excessive worry is a hallmark symptom of anxiety disorders, as these conditions are characterized by a persistent state of apprehension and concern that often exceeds the actual threat posed by the situation. Individuals with anxiety disorders may find themselves ruminating over various aspects of their lives, including health, work, or social interactions, leading to significant distress and impairment in functioning.

In contrast, increased focus and motivation are generally not associated with anxiety disorders. While some individuals might experience a temporary boost in focus due to heightened arousal, anxiety typically hampers a person's ability to concentrate effectively. Additionally, relaxation techniques are strategies used to manage and reduce anxiety rather than symptoms of anxiety disorders themselves.
