“Those final moments were especially tough,” a family insider tells Life & Style. “There were a lot of hugs and tears.”

Now at home alone with the couple's four daughters — Gia, 15, Gabriella, 11, Milania, 10, and Audriana, 6 — the 43-year-old is feeling very lonely.

“The nights without Joe have been very hard,” the insider reveals. “If they didn’t have children, Teresa would be curled up in a ball.”

But thankfully, the duo's oldest, Gia, has stepped up to the plate, helping around the house just like she did while the reality star was serving her own jail sentence.

"Gia is wise beyond her years," the insider adds. "[The kids] are keeping her grounded."
