“My skull was fractured. I had a slight tear in my carotid artery,” she said in the video.

Plano police say the driver of the Porsche that Kendall was riding in on February 10 was speeding, lost control, and slammed into a tree.

“I had two friends that passed away in the car accident, and I wanted to live for them,” she said.

Sixteen-year-olds Samantha Sacks and Lilly Davis both died at the scene.
