“Anxiety attack” is not a formal, clinical term, but one that is used by many people to describe all sorts of things, from feeling worried about an upcoming event to intense feelings of terror or fear that would meet the diagnostic criteria for a panic attack. In order to understand what someone means by “anxiety attack,” it is necessary to consider the context in which the symptoms occur.
There is a long list of signs and symptoms of an anxiety attack. But because each body is somewhat chemically unique, anxiety attacks can affect each person differently. Consequently, anxiety attack symptoms can vary from person to person in type or kind, number, intensity, duration, and frequency. If your symptoms don’t exactly match this list, that doesn’t mean you don’t have anxiety attacks. It simply means that your body is responding to them slightly differently.
