No other suffix in the English language is as versatile and subject to abuse than phobia. Tack it onto any other word and you've just invented yourself a new anxiety disorder. You might just get the nascent term into the DSM, the psychiatrist’s bible for diagnosing mental illness, provided, of course, that you have a working knowledge of ancient Greek. Like its fellow suffix, -gate, -phobia is constantly giving birth to new words to describe social situations and, sometimes, real clinical diagnoses. Still, phobias are real and terrifying, both the specific kind, like arachnophobia (fear of spiders) or acrophobia (fear of heights), and the social type, like islamophobia or xenophobia, and the lives of the sufferers are severely crippled by their disorder. Let us fearlessly take a look at the worst phobias a person can have.
