Sаrаh’s friends, Tоbiаs and Aries, are very wоrried abоut her. For the past two months, Sarah has been spending less and less time with them and often isolates herself in her bedroom. When they convince her to participate in activities she used to enjoy, like reading, swimming, or collecting seashells, Sarah shows little enjoyment in them. During one recent trip to the beach, Sarah had her back to Tobias and had bent down to pick up a seashell. When he called to her and received no answer, he tapped her on her shoulder to get her attention. In response, Sarah jumped with a loud scream and began to cry. Previously an avid theater goer, Sarah has been avoiding the local theater entirely. She also has been avoiding Aries’ brothers, who have blond hair. About two months ago, Sarah was held at knifepoint by a blond-haired man in a mask. Sarah has not spoken of the event since. Which disorder is Sarah most likely suffering from?
