The 30-year-old British pop star reveals upon gaining fame for her 2010 song, "Lights," she started questioning her worth as a musician, reported Entertainment Tonight.
"My new life as a pop star certainly wasn't as glamorous as all my friends from home thought. Secretly, I was really struggling physically and emotionally. I think part of what sparked my panic attacks was not feeling confident enough to believe in myself.
"I was scared I wasn't as good of a singer as everyone thought I was. And as the stakes grew, I was afraid of letting everyone, including myself, down," she says.
"I told myself that this was exactly where I was supposed to be and if other people believed in me, I had to start believing in myself," she says.
