“I’m a crusader for being yourself and loving yourself, but I’ve found it hard to practice," the 26-year-old singer said in a statement. "I’ll be unavailable for the next 30 days, seeking treatment for my eating disorder … to learn to love myself again, exactly as I am."
Ke$ha began a fitness regime last year after tabloids published photos of her in a bikini back in 2011.
"Im doing a juice cleanse and I want to die," she tweeted last April.
