Anxiety is a physiological and psychological response that occurs when the mind and body encounter stressful, dangerous, or unfamiliar situations. It manifests as a feeling of discomfort, distress, or apprehension before a significant event. However, people with anxiety disorders frequently have intense, excessive and persistent worry and fear about everyday situations. Often, anxiety disorders involve repeated episodes of sudden feelings of intense anxiety and fear or terror that reach a peak within minutes (panic attacks). Anxiety is characterized by feelings of tension, worried thoughts, and physical changes. Anxiety is considered a future-oriented, long-acting response broadly focused on a diffuse threat.

There are several types, including generalized anxiety disorder, specific phobias and social anxiety disorder. Anxiety is fundamentally a state of tension or disquiet inside of us that we desire to resolve, and it is most accurately defined as stress directed toward some future event or uncertainty. A classic definition of anxiety is an intolerance of uncertainty. People with an anxiety disorder may experience excessive fear or worry about a specific situation (for example, a panic attack or social situation) or, in the case of generalized anxiety disorder, about a broad range of everyday situations.
