To begin with, before I lay out frequent panic or anxiety attack symptoms, I’d like to take a minute to clarify that a “symptom” is a thing that doctors take note of to distinguish individual ailments and diseases. Generally anxiety disorders aren’t medical diseases. They are behavioral issues. That is to say that there is likely absolutely nothing physically wrong with you that is producing panic and anxiety attacks, but instead you have problems with anxiety attacks because you are reacting to anxious thought patterns and “what if” thoughts.
