She saw her daughter being attended to by medics on a makeshift stretcher and rushed over. 
'They were doing CPR and had the balloon over her mouth trying to keep her alive,' she told the Daily Star Sunday.
'I was talking to her. I was saying, "Please Georgina, please just try, it’s mummy, please try".
Mrs Callander said she was holding her daughter's hand and rubbing her leg in the ambulance to hospital. 
When they got there she waited outside a threatre while medics tried to revive her. 
Doctors don't spend more than 25 minutes doing CPR. A nurse invited Mrs Callander in for the final two minutes where she held her daughter's hand until they stopped.

'By this time I was hysterical,' she said. 'I cuddled her and held her hands. I was all alone with her and I didn’t know what to do. Then as I went out the curtains went black and I passed out.'
Moments later Georgina's father Simon and brother Daniel arrived at the hospital. 
Mr Callander said he wailed on the floor when he heard the news and then went home, drank ten cans of lager and wandered the streets for the rest of the night.
He said he didn't leave his bedroom for two days. 
In August Georgina's family warned the Government to 'open its eyes' to the terror threat - or more parents could lose children. 
In a statement released through Greater Manchester Police, her family said the teenager's life had been cut short by 'evil, evil men prepared to ruin lives and destroy families'.
It added: 'I wish I could say that Georgina is one of the last to die in this way but unless our Government opens its eyes we know we are only another in a long line of parents on a list that continues to grow.'

Miss Callander, from Chorley, was in her second year of studying health and social care at Runshaw College in Leyland, Lancashire.
She was 'loving life', having recently passed her driving test, was 'doing great' in her exams and had been accepted into Edge Hill University, the family said.
The family's statement said: 'Her life was taken away after 18 short years by evil, evil men prepared to ruin lives and destroy families, for what?
'Georgina was as beautiful on the inside as she was on the outside, with a smile that was never ending.
'She always had big hugs for everyone and her life was blooming like the flowers she loved.'

The family paid tribute to the 'wonderful police and rescue services' and thanked the public, saying the 'hugs, love and kind words' from the public had 'a profound effect' on them.
Lesley Callander previously described her desperate efforts to bring comfort to the teenager's final moments to ITV news.
'I was just screaming and shouting at her. I was rubbing her hands, I was rubbing her tummy, I was rubbing her face,' she said.
'I don't know what was running through her mind.
'It was just a flicker of hope that she'd move her hand or move her leg or try and open her eyes a little, just to acknowledge that I was there, just to let me know that she was very, very poorly but she knew that I was there.'
The young music fan previously met Grande and posted a picture of the pair together on social media.
'She kept texting me telling me her tummy was turning over,' her mother said. 'She was so, so excited.'
