Her husband, Joe, was "very somber" before she left, her lawyer, James J. Leonard, Jr., told ABC News.
"I think the enormity of this entire situation hit him ... as I think it did their entire family," he said. "But these are very strong people and they're gonna get through it."
Last year, Giudice, 42, was sentenced to 15 months in federal prison for loan and bankruptcy fraud. Joe was sentenced to 3.5 years behind bars, and will begin his time after his wife is free. Until then, he will be caring for the couple's four daughters.
"I know that Joe is capable of taking care of them," Leonard said.
"She's gonna be just fine," he said. "Her focus is on her girls."
