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

Excessive worry or fear is a hallmark symptom of anxiety disorders. Individuals suffering from these disorders often experience persistent anxiety that is disproportionate to the actual situation or stressor. This chronic state of worry can impact daily functioning, leading to difficulties in concentrating, sleeping, and engaging in social activities.

In contrast, increased energy levels and heightened mood are often associated with mood disorders, such as bipolar disorder, rather than anxiety disorders. Delusions of grandeur pertain more closely to psychotic disorders, such as schizophrenia, where individuals may have false beliefs about their own importance or power. These distinctions are important to understand when identifying mental health disorders and their symptoms.
