It doesn't have to be a physical thing. It could be family stories or even simply a sharing or withholding of emotional support or information. If it's in regard to the family health crisis, it could even be that people are not sharing all the medical information, and that is causing confusion or quarrels. Or this could be in regard to some other part of your life, I don't get a strong feeling either way.

In any case, good luck with the family health crisis! Those are always hard.
