What is necessary to invest emotional energy in, according to Worden's tasks of mourning?

Worden's tasks of mourning emphasize the importance of developing and maintaining new relationships as part of the healing process after a loss. Investing emotional energy into another relationship allows individuals to experience connection, support, and love, which can help them navigate their grief. This act of forming new bonds facilitates moving forward while still honoring the memory of the person or thing that was lost. In the context of mourning, establishing such relationships can serve as a crucial step in transitioning from active grief to a more integrated life where the loss is acknowledged but no longer dominating the emotional landscape.

The other options, while potentially beneficial for a person undergoing mourning, do not specifically address the relational component that Worden highlights. Investing in a personal project can be a way to cope, but it lacks the social connection that relationships provide. Community service can promote a sense of purpose, and self-care activities are essential for overall well-being, but they do not fulfill the relational aspect central to Worden's framework.
