The heartbreaking two-word question little girl asked her dad the morning after her mum suddenly died at her art school graduation party in Byron Bay

A family is on its knees after a 37-year-old mother suddenly suffered an asthma attack and died while celebrating her graduation from art school.

Shari-Lee Bromley was in Byron Bay after her graduation dinner on November 24 when she suffered an asthma attack after ordering her first drink.

She was outside a pub with friends when she started having trouble breathing. Despite using her inhaler, she collapsed.

Mrs Bromley – mother of two girls, Indigo, seven, and Sadie, five – was treated by paramedics who began CPR and rushed her to hospital. Yahoo News reported.

Her husband Sean Croon, 48, received a phone call with the terrible news and went to Byron Bay Hospital, where he was told his wife's heart had not been beating properly for 20 minutes.

“I held her hand and felt her response,” Mr Croon said.

Shortly afterwards she died.

The next morning, the loving father faced the impossible task of telling his daughters what had happened to their mother.

They rushed into their parents' room, jumped on the bed and asked, “Where's Mom?”

Mr Croon then told them the 'really sad news' that 'mum had passed away'.

“Indigo understood, she burst into tears,” Mr Croon said. “Sadie was even more bewildered and didn't quite understand. We just held each other and cried.”

Mrs Bromley was severely asthmatic and her condition could be caused by preservatives that were so obscure they were often not listed on food and drink labels.

After her death, Mr Croon posted a heartbreaking tribute to his wife on social media, calling her his 'angel'.

“How can someone's heart be so full and yet so broken,” he wrote.

“She had thwarted death many times during her journey with asthma, except this time. I held her hand, caressed her and told her how loved she was when she passed by. And she looked like an angel in death. So beautiful and peaceful.

'Shari is an old soul, with wisdom, compassion, an innate ability to know what people need, and the courage to always do the right thing and follow her heart. Her acts of kindness were inspiring and her sense of humor made her laugh irresistible. She has helped so many people with her support, love and advice. There was nothing more wonderful in my life than Shari's love.

“Thank you to everyone for the outpouring of love and support. I love you all. We will all be fine, it's just going to be a long road, and very difficult at times, as we deal with the loss of an angel on earth who has been called to higher things.

“I miss you and love you with all my heart, Shari. You're free now.'

The family's loved ones are now raising money GoFundMe to help Mr. Croon make ends meet after he started working part-time to raise his children.
