Christie Swadling starved herself until she reached an unhealthy weight of just 31kg (five stone) because of her obsession with her idol, Miranda Kerr.
The 18-year-old restricted herself to as little as 200 calories a day in an attempt to resemble the Victoria Secret's angels.
But her desire to look like the controversially skinny lingerie models left her in hospital after her heart rate dropped to a dangerously low level, reports Barcroft TV.
The teen from New South Wales, Australia, was once a talented long-distance runner and competed in the state and Sydney regionals.
But eventually she became too weak to even walk and she even collapsed on one occasion after attempting a slow jog.
Now Christie is on the road to recovery, and after gaining 12 kg (two stone) feels she is ready to share her message to support other people struggling from an eating disorder.
