I think you would make great strides in thinking about this if you differentiated between feelings and emotions, one being pretty primitive, bodily inner states and the other outward directed, complex scripts that’s are deeply social, learned and performed and shared ways to communicate feelings (take all the different ways for example “anger”, “mourning” or “lust” are performed with totally different modes of articulation and performance between cultures, times and locations. That is: mourning is not a feeling, it’s a complex, socially learned (socialized) script that is performed in a socially expected way, that is rooted in feelings but solved a communicative, social task.

(I know nothing about this topic expect for one book about the socialization of emotions that I read a million years ago).
