just for brainstorming, do you think shy bowels is not the shyness of other people around, that could potentially threaten our safety in the loo, but shyness in ourselves that we may have an inner critic?
i think all our world's are inner lived not outer lived, thus symptoms and illness manifest in the outer world. that we cannot CURE a symptom by our outer world alone but with the inner worlds within.
"there is a disruption of thought balance in the function of ones body."

brainstorming is a great way to think about things, to learn about Who is really watching Us, the Watcher within could just be Ourselves????
