She said she's "Tired," adding, "No, I'm doing really good. And I'm actually not tired, really. I get so much energy doing all this stuff, you'd think that I'd be exhausted, but I'm actually doing really, really good."

She added, "There definitely aren't enough hours in the day."

Demi also talked about being a role model and sharing her story, explaining, "it's not about being perfect. It's about speaking about your issues and inspiring others to get help."
