answer:I do, except I have given them a name, panic attacks and anxiety attacks. The feeling of wanting to run and flee is possibly an adrenaline rush that occurs at the time. Honestly the only thing that helped me was medication for it. Because at those times, even relaxation methods or anything of the sort, made it worse. It is normal to feel like this if you suffer generalized anxiety. It is also normal to feel it if it is directly related to a fear stimulus. It becomes abnormal when it becomes debilitating or interferes with your daily functioning.
