'It's Been Difficult To Stay Sane': An Embattled Bethenny Frankel Admits She's Struggling In The Midst Of A Nasty Divorce

Bethenny Frankel says "it's been difficult to stay sane" through her contentious divorce, and custody battle, with Jason Hoppy.

"It's been hard," the former Real Housewives of New York star, 42, told Life & Style, insisting she's staying optimistic through the storm.

"For every rough thing there's a reason for it, and there's a reason you had those struggles," she said. "When you're going through a rough time, you have to say, 'I know I'm going through these hard things, and even though it's difficult to see it clearly, the light is coming at the end of it.'"

As we previously reported, both Bethenny and Jason, 41, have petitioned the court for full custody of their 3-year-old daughter Bryn in their split after less than three years of marriage.

Bethenny said the child "is the light of her life," and has been key in getting her "through this."
