"Even now I think about her. I just see her smiling ... just always full of laughs and joy and she loved people," Stephanie Younger said. "We were always together, always. She was my best friend as well as my daughter. She just feels like a hole in my heart."
Wells said she has stopped thinking about the accident all the time.
"I still have days I think about the accident but not so much," Wells told "GMA" recently. "I'll never forget the accident, but I've learned how to accept losing my leg and I'm learning more and more each day that Ashley is gone and just trying to move forward."
Last week, she got a new leg, called a V-Hold. The cutting-edge prosthetic is designed to adjust to different terrains and elevation, using a computerized socket system that moves with the patient. (Click Here for more information about the prosthetic).
She said the new prosthetic is comfortable and "feels lighter, feels like it's always with me."
"It can monitor and sense what the patient is doing," said Phil Hewett, the prosthetist from Hanger Inc. "So it knows if they are kicking, running, jumping or moving."
Wells knows how lucky she is.
"I wish I had my leg, of course, and it's a struggle and it's painful, so I get frustrated, but besides that I'm just grateful I can walk," she said. "I broke my neck and my back, so it's even a miracle that I'm walking."
Stepping out of the wheelchair and standing up for the first time "felt good."
"I forgot I was that tall," she said, laughing.
