Lady Gaga temporarily lost sight of the light.
The singer is currently promoting jazz album Cheek to Cheek, which she recorded with legendary musician Tony Bennett.
She's previously spoken about the tough times she went through last year when she suffered a hip injury and had to cancel many of the Born This Way Ball shows.
Now she's opened up about just how isolated she felt.
"I no longer saw any light. Anywhere," she candidly told German magazine Stern.
"The past few years have been really dark. I had to have an operation and 21 of my concerts were cancelled. Nobody from my team was there for me - not through my operation and not while I was recovering.
"I lay there in my hospital bed and felt like a cow. I'd been giving milk this whole time and now that I was ill and could no longer be milked, they said, 'Give us a call when the cow is better.'"
The 28-year-old credits Tony with helping her recover and thanks him for accepting her the way she is. She no longer suffers from depression, anxiety and eating disorders and also meditates to stay on the right track.
"I'm Teflon-Gaga now," she smiled. "I let everything just bounce off me."
Gaga is now back to her best and busy with the ArtRave: The Artpop Ball tour, which ends in November. She's been concentrating on the positives and recently congratulated a fan who performed on of her dances in a video that went viral.
"I know I was on vacation, but when are we going to talk about the boy who did applause choreography in the background of a news report. (sic)," she posted on Twitter.
