"It's been quite a journey. [With the criticism], I went to a dark place," Kesha reveals to the magazine. "There was a lot of not eating -- and I started to think being hungry to the point of feeling almost faint was a positive thing. The worse it got, the more positive feedback I was getting. Inside I was really unhappy, but outside, people were like, 'Wow, you look great.'"
"I was singing these songs like 'We R Who We R,' and I really believed them," she adds. "I wanted to be genuine. But I was sad and [I wasn't eating]."
Kesha now makes a conscious effort to stay healthy and to love herself.
"I realized being healthy is the most important thing I can do for myself," she stresses. "Now, I'm trying to embrace the skin I'm in. It's difficult sometimes. Every day I have to look in the mirror and make the choice to be kind to myself. This is who I am -- I have to love that."
Still, she doesn't regret any of her more questionable outfits in the past.
"No, I look back lovingly because I was having so much fun [with hair and makeup]," she reflects. " ... And before I went on stage I used to pour beer on my body [as an adhesive] then roll in a bathtub full of glitter. I don’t do that anymore because it irritated my skin."
Though don't count out her love affair with glitter just yet. "I'm not done with it forever -- there are still hints of glitter," she says.
