““There’s a term we use for it: “ambiguous grief.” It can be a life sentence. It’s a kind of unresolved grief. You might feel it if you have a child or another family member who is mentally impaired. You might mourn the person you think they could have been if things had turned out differently. That person is physically present but psychologically absent. Conversely, and this is what happens in cases of abduction, or more commonly in divorce, the child or the person is psychologically present but physically absent.””
