Ladies & Gentlemen: I have been following this very carefully for personal reasons. My wife has suffered from Agoraphobia coupled with Panic disorder for years, so I 'do' know what you are talking about.
Unfortunately she is NOT a fighter, except with me, so I can do no direct good for her, nor will she try conventional treatments. She simply states "it won't work, so why try" ?

? From my years of paranormal experimentation, I KNOW that I can help her, but it requires cooperation. sigh
Sparticus posted that he learned to control pain by simple concentration. He is quite correct. Using what I call Hyper suggestion, I was able to teach both of my grand sons complete pain control in about 15 minutes. It has come in handy a few times since.
I also found that many conditions can be duplicated, controlled, or aggravated, entirely by mental belief or suggestion. One of the least used and truly understood medical treatments, is simple Hypnosis. It can create miracles in healing, both physical and Psychologically, and if self induced subconsciously under adverse conditions, it can do precisely the opposite. It can generate basically untreatable problems and conditions.
Long, long story here, but will leave it for another day of posting, but will suggest that those with problems, study self hypnosis, extremely easy to do.
