Every Duel you missed

For the past year, a 24-year-old man has been convinced that his nose is crooked and oversized, although his relatives and his physician describe it as normal; he checks it in mirrors for hours each day, repeatedly asks his sister whether it looks deformed, and mentally compares his profile with those of strangers. He has stopped attending classes and parties because he believes people stare at his nose, yet he says he does not worry about saying something foolish or looking nervous, and he feels comfortable in groups when a mask hides his face.
