I have done what you said no one does. I have researched and surfed and read and studied and probed and went into ever nook and cranny about this problem of agoraphobia. I spent 40 years doing it and YES I did find the answer. Not only did I find the answer I wrote a book about it. I also have a blog with over 100 posts about it. Take a look!
