Anxiety is a normal part of life at times, but those with anxiety disorders have persistent and intense fear and worry about everyday situations. Anxiety disorders include a range of conditions, such as generalized anxiety disorder (GAD), panic disorder, and post-traumatic stress disorder (PTSD), where stressors such as traumatic events, life changes, and perceived risks can contribute to ongoing symptoms.

Moreover, people with generalized anxiety disorder may have a persistent concern over potential future events, to the point where it interferes with daily life.
