WP on 'Cartharsis: "In psychology, the term is associated with Freudian psychoanalysis and specifically relates to the expression of buried trauma, bringing it into consciousness and thereby releasing it permanently."
it's hard to come to terms with death, especially when you are in that vulnerable time of your life. Maybe it's not a trivial 'emotional issue' (not sure if there are any trivial emotional issues...)
Please try and realize that people are different. Not conforming to the "ideal" construct of a child in western society might not be the worst thing. Diversity in thought and opinion does not _only_ come from race and gender, it also comes from nurturing thoughts and perspectives in our own kids that might not align with the norms. This doesn't mean saying everything is great, but being an adult, and discussing various facets with them rather than shut things off.
I think it's healthy for your empathy circle to extend beyond your immediate family.
