The singer opened up about hitting a personal and professional low in 2017.

Katy Perry says she hit a personal and professional low back in 2017, leaving her "wallowing" in her "own sadness."

In an interview with Q on CBC, the pop star said she struggled with her mental health after she and boyfriend Orlando Bloom split up, and after seeing her career trajectory shift downwards.

"My career was on this trajectory when it was going up, up, and up, and then I had the smallest shift, not that huge from an outside perspective. But for me it was seismic," she said, adding that the shift that occurred after her album Witness wasn't received as well as expected "literally broke me in half."

"I had broken up with my boyfriend, who is now my baby daddy-to-be and then I was excited about flying high off the next record," she said. "But the validation did not make me high, and so I just crashed."

"Gratitude is probably the thing that saved my life, because if I didn't find that I would have wallowed in my own sadness and probably just jumped but I found the ways to be grateful," Perry said.

Perry said that she was able to cope with her mental health struggles when she turned to her faith.

"Hope has always been an option for me ... because of my relationship with God and something bigger than me," she said. "If I'm the only one controlling my destiny of course it's going to be, like, I am going to drive it into the ground."

Perry and Bloom, who are now engaged, split up in 2017, but were spotted together again by the following year. In 2019, they got engaged on Valentine's Day, and earlier this year, it was announced that Perry is pregnant with the couple's first child together.

Perry previously spoke out about experiencing depression in an interview with Vogue Australia in 2018, telling the magazine she "had bouts of situational depression." Earlier this year, she also discussed her low points in 2017, adding that her upcoming album will delve into that journey.

"At one point [I] became clinically depressed and, you know, had to figure some things out and go through a journey," she said. "I think that what's coming musically for me is songs about that journey and getting to that okay place."
