Reacting to "tragedy"
The portrayal of reacting to a perceived "tragedy" has been attempted by cinematic drama.
I think to Lady Mary Crawleys reaction to the death of Matthew. Or Lila Gahertys reaction to Jason Streets debilitating accident. It's usually portrayed in outbursts and dramatic moments, but the even more depressing reality is that it's a slow and muted experience, a cessation of emotions (some might liken it to deadening of feeling).
The biggest missing piece is a lack of reframing that must occur for the person to truly move on. That if she sees it as a tragedy, there remains little hope or desire for the future. Rather there is a necessity to view the event as a test, or change, or stepping stone to something greater. For who gets motivated to embrace life when she views the best as being in the past? A reframing that the best is yet to come must occur.
Otherwise, Manchester by the Sea does the most realistic job at portraying the aftermath of tragedy, in its muted grief. "There's nothing there" shouted Lee at his ex wife.
