Anorexic given just 48 hours to live when her weight hit FOUR stone makes remarkable recovery - and shares harrowing photos to raise awareness.

An anorexic teenager who weighed little over four stone and given 48 hours to live has shared harrowing photos of her illness after a miraculous recovery.

When Gemma Walker was diagnosed with anorexia nervosa and bulimia aged 14, doctors warned she would die without treatment.

The teen weighed a tiny 4.5 stone forcing her devastated parents to consider palliative care.

Over the next seven years, she was admitted to hospital three times with one emergency care and two long term psychiatric and re-feeding admissions.

Now 22, Miss Walker has posted both harrowing pictures and those which show her remarkable recovery to celebrate six months of being well. 

She hopes that by sharing the shocking photos of her skeletal form and her return to health, she will inspire other people battling eating disorders.

'It's hard for me to look back at the photos, not so much how I physically looked but more so the feelings,' she said.

'I look at each photo and remember exactly how I was feeling, or what was behind that photograph.

'I felt numb, the days just melted into each other and I wished each day by, hoping that I would just pass peacefully in my sleep. My family and I were ready to let me pass.'

Her father Steve revealed seeing pictures of is daughter at her worst brings back the pain and constant anguish he saw.

'They were the hardest and most terrifying years of our lives, checking on her each morning to see if she was still breathing, to see if her weak heart was still beating,' he said.

'Some nights we would just sit on the floor by her bed, just to be with her, there was nothing else we could do.'

Miss Walker, from Gold Coast, Australia, was severely depressed would trick doctors to think she was gaining weight by wearing gym weights and began to self-harm to cope with the pain.

And when she did take steps to recover, she found she struggled with binge eating and suffered from re-feeding syndrome. 

The desperate teen would consume 6500 calories in just 20 minutes causing her to pass out and experience hallucinations.

My weight gain was very rapid. In less than seven months I put on 40 kilograms, tripling my body weight, however I was at my worst mentally.

'People believed I was better because I looked healthier that I was better and no longer anorexic.

'Chronic bingeing and bulimia lasted almost 18 months, it was a complete 360 from strict obsessive rules to complete loss of control.'

'I also have my beautiful parents to thank, they literally been through everything with me, it's only now that I realise what incredible, loving parents they are.

'I am the happiest I've ever been now, it's such an amazing, surreal feeling.

'I do believe that I have fully recovered and that my anorexia is now just a huge chapter that has closed.'

Mr Walker said her recovery has given the family 'so much joy.'

'She is full of energy and hope, which is something we never thought we'd see in our daughter again,' he said.

'Seven years is a long time to have your baby suffering, a long time to have your child numb, with no voice, no personality - just a lethal controlling obsession.

'She has overcome this by herself, we have merely been by her side.'
