"It's at the bottom of the rock, devastated," a source tells CNN. "She knows that she could be gone for a long time, and that is horrifying for her."
Lofflin and her husband had previously pleaded guilty in April to charges of conspiracy to commit fraud and money laundering. Prosecutors say she and Januli paid $ 500,000 for a fake charity to bring their two daughters to the University of Southern California, falsely identifying them as recruits. They face up to a maximum of 45 years in prison on charges.
Asked by CNN how her marriage had been affected by this scandal, a source said she was "out of tension."
"All she wanted was the best for her daughters and she wanted people to see it," the source added, "She's definitely regretting the way she has handled herself since it all came out."
] The source notes that Loglin and her daughters are "closer than ever."
CNN contacted a Loughlin representative for comment.
Loughlin is awaiting trial on charges she has already pleaded not guilty to. The next court date for the case is set for November 20.
