Clara Malagon, 22, was on-duty on the night of the atrocity and saw the horrific injuries inflicted in the blast.
A bomb exploded in the foyer of Manchester Arena moments after Ariana Grande left the stage on May 22, 2017.
Witnesses told how nuts and bolts were sent flying as suicide bomber Salman Abedi detonated a device in his backpack - dozens were hurt and 22 killed.
Dr Ignacio Malagon, a consultant anaesthetist at Wythenshawe Hospital, wept as he told the inquest:
''It was traumatic for her and I rang her, I was in hospital too, and I said to her: 'Are you OK?' And she said: 'Yeah Dad, it’s really tough, I’ve seen some of the kids didn’t make it'.”
"She said some didn’t make it from A&E and she said she had seen some with their faces blown away and it was really hands on in the ICU.
“We had a long chat and I said to her that I realise this is very traumatic for her and if she was upset then she should tell her seniors, or if she felt unwell she should tell her managers. I just said to her not to worry and that it was going to be fine."
Miss Malagon had counselling, the inquest into her death heard, but less than two months after the terror attack she was found hanged in her flat in Manchester city centre.
In a statement her GP, Dr Gill Aitken, told the hearing: ''She came back to me and said she was feeling low and crying, and feeling apathetic. Whilst there was no trigger, I believe this was work related."
Originally from Twickenham, South West London, had become a critical care nurse at Manchester Royal Infirmary in 2016.
She was a keen rower and enjoyed cycling running and walking. She also played the viola and had taken up ballet and flamenco dancing. May her soul rest in peace.
