Your mother retired two weeks ago after 40 years as a nurse at the same hospital. She didn't want to retire — hospital policy required it at 67. She told you on the phone last night that she 'doesn't know who she is without the hospital' and 'feels like a ghost in her own house.' She is not clinically depressed; she is grieving. You are writing her a handwritten card — the kind that arrives in the mail. She is not on social media and values handwritten things. Do not suggest hobbies, volunteer work, part-time shifts, or any way to 'fill the time.' 120-180 words. Just the text of the card itself, no preamble.
