Question

Quizplus · Accepted Answer

This is an example of a phobia. A phobia is a strong, persistent, irrational fear of an object or situation; the person feels driven to avoid it. The situation in the question is not an example of hypochondria, an obsession, or a delusion. A hypochondriac is a person who is morbidly worried about his/her own health and/or feels sick with no actual basis for that assumption. An obsession is an unwanted, persistent thought or impulse in which logic will not purge him/her from his/her consciousness and is intrusive and senseless. A delusion is a firm, fixed, false belief that is irrational and that a person clings to despite objective evidence to the contrary. Instead, the situation in the question is an example of a phobia. A phobia is a strong, persistent, irrational fear of an object or situation; the person feels driven to avoid it.
