Which of the following are common signs of anxiety disorders?

Excessive worry and restlessness are hallmark symptoms of anxiety disorders. Individuals who experience anxiety often find themselves caught in a cycle of worry about various aspects of their lives, such as job performance, health concerns, or relationships. This chronic rumination can lead to heightened levels of stress, making it difficult for them to relax or feel at ease. Furthermore, restlessness is a physical manifestation of anxiety, where individuals may feel unable to sit still or may engage in fidgeting behaviors. These signs are closely linked to the body's response to stress, characterized by increased arousal and tension.

While the other choices may relate to different mental health conditions or states, they do not encapsulate the specific qualities associated with anxiety disorders as profoundly as excessive worry and restlessness do. For instance, excessive laughter and joy are typically not symptoms of anxiety but rather may indicate a more positive emotional state or an unrelated issue. Low energy and fatigue could signal depression or burnout, which are distinct from the anticipatory fears characterizing anxiety. Compulsive eating habits may stem from various psychological factors, including stress or emotional eating, but they do not directly reflect the core symptoms of anxiety disorders.
