Experts say COVID deaths are leaving millions bereaved. For some, the intense grief never recedes, making daily life almost impossible. Mary-Frances O'Connor, a clinical psychologist at the University of Arizona specializing in grief and its physiological impacts, likens this process to healing a broken leg: For the majority of people, rest and a cast will allow it to return to normal. Yet for a subset, a complication will arise – an infection or secondary trauma to the area – that prevents it from healing properly without more intensive intervention.
