I just realized this thread seems to mostly be about Agoraphobia. At least for me...
"...is an anxiety disorder characterized by anxiety in situations where the sufferer perceives certain environments as dangerous or uncomfortable..."
"Agoraphobia is a condition where the sufferer becomes anxious in environments that are unfamiliar or where he or she perceives that they have little control."
"Triggers for this anxiety may include wide open spaces, crowds (social anxiety), or traveling (even short distances). Agoraphobia is often, but not always, compounded by a fear of social embarrassment, as the agoraphobic fears the onset of a panic attack and appearing distraught in public."
"The sufferer may go to great lengths to avoid those situations, in severe cases becoming unable to leave their home or safe haven."
"These situations include, but are not limited to, wide-open spaces, as well as uncontrollable social situations such as the possibility of being met in shopping malls, airports, and on bridges."
