A 22-year-old British woman says she suffers from such a severe phobia that she can't walk into a supermarket without having a panic attack. The cause of these attacks? Cheese. Melissa North says she developed her cheese phobia as a young child when a friend gave her cheese on toast. Since then, she bursts into tears and cold sweats whenever she sees it. She says, "It just looks awful – so gooey and disgusting. It makes me feel sick." The height of her cheese phobia came when she was 15. She says the kids at school knew about it and teased her by throwing cream cheese at her. North says her friends and family still mock her phobia, but she insists it's a serious problem.
