At my worst point w/panic disorder my panic attacks would occ. last 6+ hrs.i cant find an article that says they can last this long.am i the only one?

You are certainly: not the only one who suffers from panic disorder. There really is no timetable for how long a panic attack should last, as most people can have the anticipatory anxiety prior to and after the actual episode which makes it feel like the attack will last forever. Certain types of panic disorder, such as that with agoraphobia, will last as long as you are exposed to the open environment.
