Although she still has a long road to recovery ahead of her, Aimee Copeland, the Georgia student battling flesh-eating disease, reached a milestone over the weekend when she spoke for the first time in weeks.

Copeland’s father, Andy, told an NBC affiliate that the 24-year-old grad student spoke on Sunday. “The first thing that she said was, ‘Woah.’ She said, ‘Wow, this is amazing.’ She was shocked to hear her own voice,” he said.

Copeland has been battling a life-threatening bacterial infection since cutting her leg on a homemade zip line on May 1st. Since then, doctors were forced to amputate her left leg, hands and remaining foot in an attempt to control the terrible disease.

Still, Copeland’s father said he’s thankful that his daughter is even alive. “I would say her existence, her life, is a miracle,” he said. “Because when she arrived over at Doctor’s Hospital, she basically had a less than 1% chance of survival.”

Copeland is still in critical condition, but is currently breathing without the assistance of a ventilator. And last week, she was able to sit up in a chair.
