In an interview in the October 2012 issue of Australia's WHO magazine, Nicole Kidman opened up about life after her 2001 divorce from Tom Cruise, which she described as "the loneliest, loneliest existence."

Then when it didn't work out, I had to really dig deep and find my way through depression, but I have no regrets about all of it. It was all a part of growing up."
After seven years of marriage, Reese Witherspoon filed to divorce Ryan Phillippe in November 2006. After the split, Phillippe admitted that he struggled with depression. In a 2008 interview with W magazine, he described the period as "the darkest, saddest place I had ever been." "It was a struggle--there were a good four or five months of not being able to get out of bed. It was the worst time in my life," he said. "You get through it.

In a 2007 interview with Parade magazine, Halle Berry admitted to being so distraught after her 1996 split from baseball player David Justice that she contemplated suicide. "I was sitting in my car, and I knew the gas was coming when I had an image of my mother finding me," she told the magazine. But Berry reportedly claimed that Parade "sensationalized some old material" about her suicide attempt, noting that the information was actually pulled from earlier interviews with Larry King and Oprah. (Parade denied the accusation.)

A year later, she elaborated on the pain she felt in the wake of the split: "My professional life was soaring, but my private life was in ruins," Contact Music quoted Thurman as saying.
