how do you feel about what she said?
personally, i do think that physical expression of symptoms can be related to emotions, on my course, we are learning quite a lot about that - however, i can also see the danger in it being used in a way that might not sit well with you, its individual to you and your reactions
the symbology of not pooping is interesting, psychodynamics places a lot of credibility on holding onto stuff that way and how it relates to your state of mind.
that sort of perspective can be useful, however i think it can sit quite awkwardly with grief and western perspectives so you have to be open to hearing it - do you feel its been useful?
