The phrase "in grief" is commonly used to describe the emotional pain and sadness a person experiences after a loss. However, there are many synonyms that can be used to describe the same feeling. "Heartbroken" conveys the overwhelming sadness and pain of loss, while "bereaved" suggests a sense of loneliness and isolation. "Melancholy" and "wistful" depict a more contemplative and reflective state of mind, while "devastated" and "crushed" emphasize the intensity of the emotion. Ultimately, the choice of synonym depends on the speaker's intention, context, and tone, but they all capture the profound sorrow and deep mourning of grief.
