Which of the following mental illnesses is characterized by extreme worry and panic?

Anxiety disorder is characterized by intense feelings of worry, fear, and panic. Individuals with this mental illness often experience excessive anxiety about various aspects of life, which can manifest as panic attacks or overwhelming feelings of dread. Symptoms may include restlessness, rapid heart rate, sweating, and difficulty concentrating, all linked to the heightened sense of worry typical of anxiety disorders.

In contrast, post-traumatic stress disorder generally arises after experiencing a traumatic event, focusing more on reliving that trauma and avoiding reminders. Bipolar disorder involves significant mood swings between depressive lows and manic highs, making panic and worry less of a central theme. Depression is primarily marked by persistent feelings of sadness and a lack of interest in activities, rather than the extreme worry and panic that define anxiety disorders. Each of these conditions has unique symptoms and characteristics that distinguish them from anxiety disorder.
