here is my take on worthless that I wrote for the Daily Echo ... maybe that will give you something to use the word for:

"The life we build can fracture in a flash, leaving us feeling worthless. True value is not found in the life built, but in your resilience and inner strength to navigate the break and rebuild." -- ShadowsPub

With your values, resilience, and inner strength guiding like your North Star, you'll be able to navigate life's fractures and write your new chapter.
