안녕하세요. 답을 알수 없는 문제가 있어 도움을 청합니다.

i once saw a young girl who had spent months in hospital with paralyzed legs. as a last resort, her parents called in a psychologist, and the next day she was walking. she told me a story about her drawing that gave a lead to the secret problem. she felt guilty because she was growing too big-boned to be able to become a professional ballet dancer. her family had invested so much in her ballet lessons, and had expected a brilliant future for her. the psychologist helped her to see her many other talents she could develop, and that she needed no excuses for stopping serious ballet. she got out of bed and walked. the paralysis had been real, but its solution was not medical. it was the recognition of the unconscious conflict that cured her.

윗글에서 밑줄 친 paralyzed legs가 상징하는 것으로 가장 적절한 것을 찾아 쓰시오.
