A familiar question arrives: how are you? You could answer with the loss, again. Or protect everyone from the honest answer, again. Naomi says what she is carrying when she returns to Bethlehem.
She asks to be called Mara, bitter. Ruth's story lets her say it. It also shows Ruth staying beside her and practical care entering a life Naomi calls empty.
The ending gives no timetable for your grief. You don't need a new name or a useful lesson by Friday. Tell someone safe the truth. If a kindness reaches you today, receive it without requiring it to fix the whole story.
A question to sit with
What part of me has become hard to see beyond my loss?
You can take this slowly.
