F. Scott Fitzgerald was a notorious hypochondriac. As Kelly Boler points out in an article for Pine Magazine, he was also prone to a certain degree of self-diagnosis: 'In 1936, he convinced himself he had tuberculosis, and self-prescribed a nice, quiet recuperation in the mountains at the glamorous Grove Park Inn, which advertised itself as “the finest resort hotel in the world.”' ('F. Scott Fitzgerald in Asheville: The Crack Up', 21 August 2006).
He was certainly left in poor health following years of alcohol abuse. He died on 21 December 1940 after suffering two heart attacks.
