Because the 32-year-old Rosales was immobile for so long, everyday duties such as buying groceries, job hunting and shopping for clothes now prove to be daunting tasks. But she draws on enormous amounts of willpower and patience to adjust to her new life in a bid to prove she's capable of not only caring and providing for herself, but her nieces and nephew she's hoping to adopt.
