"I feel like I lost my sanity at one point," Smith says of the time surrounding her 2010 single "Whip My Hair."

Smith continues: "I had just stopped doing singing lessons and I was kind of just in this gray area of 'Who am I? Do I have a purpose? Is there anything I can do besides this?' "

"After the tour and the promotion and all that, they wanted me to finish my album," she says. "I was just like, no, I'm not going to do that. After all of that settled down and it was a kind of lull, I was just listening to a lot of dark music and it was so crazy and I was just plunged into this black hole and I was like cutting myself."

A visibly emotional Pinkett Smith says she "had no idea" her daughter was self-harming, and Banfield-Jones says she "never saw any signs of that."

"When were you cutting yourself? I didn't see that part," a stunned Pinkett Smith says. "Cutting yourself where?"

"On my wrist," Smith says. "You can't really see it, but there's still a little something there."

"I honestly felt like I was experiencing so much emotional pain but my physical circumstances weren't reflecting that," Smith says.

Smith revealed that it has been five years since she stopped self-harming. "I never talk about it because it was such a short, weird point in my life," she says. "But you have to pull yourself out of it."
