A "devoted" mum-of-three died suddenly after helping her eldest child get ready for the school.
Michaela Bateman, 34, was taken to hospital after feeling ill on the morning of September 29, but later died from a pulmonary embolism.
She was preparing her eldest son, George, ready for school and called to her mum, Sharon Massingham, from the bedroom, who had been staying, saying she was in pain.
Michaela was taken to Frimley Park Hospital in Surrey where she suffered a cardiac arrest soon after arriving and staff told the devastating news that she was "gravely ill".
Sharon, who followed the ambulance to the hospital with her son Craig, said the doctors had to "work" Michaela's heart and breathing for her.
She is survived by nine-year-old son George, Colby, two, and five-month-old Cahlia.
Sharon, 52, told Surrey Live : "She was in agony and saying it was in her rib cage. She suffered from pancreatitis, which I thought it was." She said the pain "grew worse and worse" and so she called an ambulance for her daughter.
She added: "They worked on her for about an hour and a half but they had to turn the machine off as there was no more they could do for her. She died from a catastrophic pulmonary embolism.
"She was a devoted mum and she used to go on date nights with her eldest and go bowling and for a meal.
"We lost my mum on September 19 - Michaela and she were very close - and then 10 days later we lost my daughter. So it's been a double whammy.
"It's a case of having to cope with it because we have the children."
Sharon revealed that either her or her husband will have to give up their jobs so they can take care of their three grandchildren.
She added: "There just isn't any government help you can get because we're the grandparents and so unfortunately one of us has got to give up work as well."
Michaela's brother, Craig, said: "It's been really hard and a struggle to come to terms with it all. It's hard to explain when someone like that passes - losing your sister is horrible."
A fundraiser was set up by Michaela's friends to help "provide Michaela's family with some financial support for her funeral" and the "care of her three beautiful children".
At the time of writing, donations more than doubled the initial target of £3,000 as it reached £7,415.
