In a way, yes. It’s called “Failure to Thrive.” Neglected babies and children often die due to lack of love and affection even though they have food and water available to them. The elderly who’ve lost long-term spouses sometimes just lie down and die soon after their loved one passes. 19th century literature is full of spurned young and middle-aged lovers dying from it, but as a nurse, I’ve really not seen anything like it outside of the age groups mentioned above. I’ve seen an awful lot of love-sick young people, though.
