This is very interesting. I am sorry I don't have any info on this but I did actually cry both yesterday and today. I didn't know there was an emotional aspect to fluches. But I know that the liver in Chineese Medicine is closely connected to and sensitive to anger and stress and strong emotions in general. I let my sadness out little by little by crying a bit here and a bit there. Too much sadness is bad for the liver said my old qigong teacher.
Hope you'll feel better soon.
