Is agoraphobia ONLY for those who fear social settings as a source of panic in itself or can it be caused by something else? I, for example, am not triggered by people or social events. My panic attacks most often result from physical symptoms or mental thoughts/anxiety as a sufferer from health anxiety. THEN, if I have a panic attack in a public place, I fear going to those places by fear of having another panic attack there and sometimes reinforces itself to the point where I almost can't or can't leave home.
The result is the same, but not triggered by what seems to be the wide definition of agoraphobia.
