While Copeland's physical recovery has astounded, her psychological recovery is hard to predict, according to Trivedi.
"A lot of it will have to do with what kind of progress she's making medically. Each time she has a complication it will make it more difficult to move on from the event," he said. "This is more of a marathon than a sprint, and there will be good days and bad days."
Copeland, who was completing her masters in psychology at West Georgia University before the accident, may be more resilient because of her background.
"The fact the she was studying psychology and was interested in helping others may give her a positive outlook in terms of what to do with these new challenges," he said. "But it's a lot easier to give advice to other people than it is to take it ourselves."
Trivedi said Copeland's family, too, will need support in the days and weeks to come.
"Parents have hopes and dreams for their kids," he said. "Once they get over initial fact that she has survived, they'll start thinking about what it means for her and the rest of her life. That's a sense of loss, too. And they're going to grieve as well."
