Naomi Judd is opening up about her "extreme" and "life-threatening" fight with depression, as well as about her complicated relationship with her daughter, Wynonna Judd, wanting to provide hope for others who can't quite see the light.

Judd, 70, recently released a bookRiver of Time: My Descent Into Depression and How I Emerged With Hope. With complete candor, the singer reveals the demons that have been haunting her: severe depression, she tells ABC’s Robin Roberts in a recent interview. Together, Naomi and Wynonna Judd were known as the acclaimed country music duo the Judds -- but once they stopped touring in 1991, following Naomi Judd's diagnosis with Hepatitis C, she began spiraling downward.

“They see me in rhinestones -- you know, with glitter in my hair -- that really is who I am. But then I would come home and not leave the house for three weeks, and not get out of my pajamas, and not practice normal hygiene," Judd reveals. "It was really bad.”

During the interview, Judd -- who spent time in several psychiatric wards -- points out physical features that have been affected by her medications: Her hands shake, and her face swelled up "like a balloon."

"I really haven’t been eating ice cream and candy," she says with a laugh. "I really haven’t.”

Some of the difficulty came from the fact that Judd was "treatment resistant."

"They tried me on every single thing they had in their arsenal," Judd shares. "It really felt like, if I live through this, I want someone to be able to see that they can survive."

Although the Judds reunited for the Power to Change Tour in 2000, and for a residency, Girls Night Out, at the Venetian in Las Vegas, Nev., in 2015, Naomi Judd reveals that she and her daughter are currently "a little estranged from each other."

“I love her, but there are just times we need a break from each other,” Judd says. “If she sees this -- and I hope she does, ’cause the smartest thing is for all of us to feel known, no matter what’s goin’ on, be truthful -- I think she’ll say, ‘Good for you, Mom, for finally being willing to talk about the bad stuff.’”

River of Time: My Descent Into Depression and How I Emerged With Hope is available on Amazon.
