SAN DIEGO -- San Diego got to know 18-year-old Brittany Saber when she got out of her wheelchair and walked at her graduation from Westview High School.

Two years ago, Brittany was in a car that was rear-ended by a drunken driver. She was pinned in the backseat, and the crash left her on life support for six months.

Saber fought to walk at her graduation six months later.

Another year later, Brittany has improved leaps and bounds. She does not need a wheelchair while making up credits at Westview High School.

Tiffany Buck, one of Brittany's teachers, said, "She's such a driven young lady, and she has a lot to be proud of."

"I had to work really hard going to therapies," said Brittany.

Saber has been doing riding therapy at the Magic Horse Ranch.

"It's awesome. I learned to regain more balance and control," said Brittany.

While she has improved, her family's financial situation has not. Brittany's medical bills now total $4.4 million.

"Eventually, the money problems can be worked out. It may take a few years … but Brittany only had once chance to get better," said Brittany's father, Dan Saber.

The family's insurance is tapped out, and now Brittany's therapy could also go away.

The Sabers receive money from California Children's Services, but that funding could be a victim of massive state budget cuts this summer.

The Sabers said the debt is worth it.

"Just watching her every day; she does something different. Her personality's coming back. The old Brittany is slowly, slowly coming back," said Brittany's mother, Alyesha Saber.

Brittany's teenage spirit is back, the family said. She said she misses driving and boys.

"Yes, I'm on the prowl," said Brittany.

The woman responsible for the crash that injured Brittany had no insurance, and she is currently serving five years in prison.

Brittany will be done with high school in January and plans to go to college to become a nurse.
