Sia is John Caldwellreflecting on working through a tough time in her personal life.

Next year, the "Chandelier" singer is set to release her album, Reasonable Woman, which will serve as her first in seven years. And as the Grammy nominee—who split from filmmaker Erik Anders Lang in 2016 after two years of marriage—recently shared, her creative process was put on pause as she dealt with a bout of depression following their breakup.

"The truth is that I had just been, every now and again, writing a song here or there for the last six, seven years," Sia said during a recent interview with Zane Lowe on Apple Music 1. "I got divorced and that really threw me for a loop. That was such a dark time that I was in bed for three years, really, really severely depressed. I couldn't really do anything for that period of time."

However, the songwriter was eventually inspired to begin creating music once again.

"Just little bits and pieces here and there, but it was really hard to get me out of bed," she continued. "And then finally it just turned out we had enough songs to make an album, enough good ones."

In December 2016, Sia and Erik confirmed they had broken up a little more than two years after privately tying the knot.

"After much soul searching and consideration we have made the decision to separate as a couple," the pair told E! News at the time. "We are, however, dedicated to remaining friends."

Three years after her divorce, Sia expanded her family by adopting two 18-year-old boys who were aging out of foster care at the time, as she revealed in 2020. The 47-year-old also found love again, tying the knot with Dan Bernard in an intimate Italian ceremony earlier this year.
