Claire Jarvis's loved-ones have been left shocked after the 27-year-old passed away at home.
Claire leaves her boyfriend Robert Hollands, 24, and her three-year-old young son Harry Hollands.
Speaking on behalf of Mr Hollands, close friend Gavin Still spoke of their grief.
He said: "It's shock at the moment, sheer shock. Everyone is absolutely devastated."
Mr Still said Miss Jarvis – who had worked at Asda in Thames Way, Gravesend, for 11 years – was a person who had a smile for anybody.
He said: "She was a really bubbly person and always had a good thing to say about a bad person. She was everyone's mate and always made a bad situation good."
Mr Still said Miss Jarvis was a dedicated partner and mum and that the news was still sinking in for her loved ones.
He added: "She was a ridiculously wonderful mum and she was a really good partner to my friend.
"Everyone has problems but you don't realise how petty they are until someone is gone."
Miss Jarvis was a popular member of staff at Asda and her colleagues are all grieving her death on Friday.
A statement issued from the supermarket said: "It can't be put into words how much Claire is going to be missed at the store, both on a professional and personal basis.
"She was more than just a colleague, she was a friend to everybody.
"She had been at the store for a very long time and our heartfelt sorrow goes out to Claire's friends and family. We will support them in any way we can."
Mr Still has created a donation page in memory of Claire, who had lived in Cliffe, near Rochester, since Christmas.
"She was a ridiculously wonderful mum and she was a really good partner to my friend..." - friend Gavin Still
He said: "I'm hoping to reach out to as many people as possible.
"Anything we can get will help, £1, £2 or £5, a grand total of £20 would help. We just want to show there are people out there that love her."
Family hope to use the money to support Claire's son and fiance.
