What struck me most about this article was the positive reframe Wortman presents, "what matters to me now?" What mattered before the loss is most likely very different from what matters now, and the process of identifying this shift may provide a renewed sense of purpose and joy. For example, loss of a spouse may shift focus to being the best parent or grandparent you can be. Or loss of a loved one may increase your desire to help prevent the same thing from happening to someone else (e.g. Mothers Against Drunk Driving or Team in Training). Engaging in this new purpose may help increase positive emotions over time and even strengthen family relations.
