A year after reaching her lowest point, Dalton said the therapy has helped her redefine her goals and her life.
"It's made me so strong and stable in my mind , and in my values, and … I feel like I can take on the world," she said.
Dalton has also reclaimed her passion for what she loves most: horseback riding.
"Now it's just different," she explained. "I just come out here and for me, riding is more like the day to day, grooming the horses, getting on, romping around the field, playing with the fence."
And when model Renn finally broke the grips of anorexia, she discovered her true calling.
"I turned it around by making a final decision," she said. "I could die for this job. Why am I going to die for this job? That … doesn't make sense to me. My whole idea of beauty is just warped and wrong. I need to change, and I need to be a better role model instead of a dying model."
And that's exactly what she did. Renn consulted her agency and immediately changed her career path, becoming, at the agency's suggestion, a plus-size model.
Ironically, Renn is actually more successful at her natural weight. Back at 165 pounds, she signed with the Ford Agency as a plus-size model. She landed a prestigious Dolce and Gabbana ad campaign and she's the first plus-size model featured in six Vogue magazines across the globe.
"I feel alive. I'm happy," she said. "I'm doing the job that I always wanted to do, which is modeling, but yet, I'm doing it at the size that I'm supposed to … be doing it at."
And by doing it her way, Renn was selected for the ultimate honor in the fashion world -- walking the runway in a couture gown with the designer himself.
"It gave me hope," she said, "because I realized at that moment that I could be a size 12." She said that walking down the runway with Jean Paul Gaultier in a haute couture dress "was just such a major moment for me … and I knew that barriers were being broken."
