Sonya and her family have been homeless since she was 3 years old. Over the years, they  have moved more than 15 times to different shelters around New York City. Moving around was hard on Sonya, At school, Sonya hid her homelessness from teachers and other students. She didn't want to be treated differently than other kids.

In sixth grade, Sonya discovered a way to deal with some of her stress (压力). She began studying dance at her middle school. “It was a way for me to express myself, instead of just holding everything  in，” she  explains.  Soon,  Sonya auditioned (试演) for a summer dance camp run by Alvin Alley, a famous dance company. She was accepted.“I was delirious，” says Sonya.

Dancing became an even more important part of Sonya's life in high school. But things were not going well for Sonya at school. Each time her family moved to a new shelter, Sonya missed school. As the second­oldest of six kids, Sonya often took care of her younger sisters and brothers. She helped them get ready in the morning and took them to school. They would be on time, but Sonya would be late.

Worrying about her family kept Sonya from thinking about her own future. That changed the summer after 11th grade. Sonya learned she would  have to go to summer school to graduate. She became determined to succeed, no matter what. “It was a wake­up call，” she says.“I had to focus on (集中精力于……) school and on myself.”

Sonya made up the work that she had missed, and finally graduated from high school. No one in her family had gone to college before. But in September 2015, Sonya enrolled (登记入学) in the State University of New York at Potsdam. She plans to become a doctor for kids and to teach dance to children who have disabilities.
