Kristin Hopkins, 44, talked to ABC's Good Morning America about her ordeal Tuesday. Both of her feet were amputated after she was rescued May 4.
Hopkins was on U.S. 285 driving through Red Hill Pass on April 27 when she skidded and her car came to rest 140 feet below the highway. She said she remembers waking the next morning in her car, which was upside down so that she was lying on what had been the roof.
"The first thing that came to my mind was, 'Oh my God, I have to go pick up my kids. It's a school day. It's Monday, it's my day to pick up the kids,'" Hopkins said.
It was thinking about her children that kept her going through the next few days, Hopkins said. She had nothing to eat and, more importantly, no liquids to keep dehydration away.
"I'm a mom, I had kids to worry about, kids to take care of," Hopkins said. "I had to keep going because they needed a mom. I couldn't leave my kids."
Hopkins had an umbrella in the car and used a Sharpie to write simple messages: "Need Dr. Hurt + bleeding."
The couple who reported the car did not realize anyone in it was alive.
Hopkins was transferred to a rehabilitation center Friday.
