Antihypochondriasis

Antihypochondriasis: noun. A disease, which leads to a stern belief that one isn't succumbing to any form of disease, even when clearly ill. The early symptoms of this is a staunch denial of a cold or the claim that one hasn't suffered from a disease for over 7 years. Late-stage symptoms include attempts at attempting to continue regular life, while feverish, claiming normalcy while vomiting or attempting to eat food, while seizing. This potentially fatal psychological disorder has no known cure, but it is believed to be caused by overly protective mothers, who manage to protect their children from disease during their childhood, but also create an illusion of invincibility.
