Stacey Pentland, from Newcastle in England was diagnosed with terminal cancer in April 2020 after being rushed to hospital with pelvic pain.
After many tests and an MRI, the mum-of-four was told the cancer had spread throughout her 'entire body'.
Pentland, who shares her children aged 20, 18, 14 and 12 with her husband Anthony, had her whole life change within 24 hours of being admitted.
"I was living a normal healthy life 35 years old four beautiful children my whole life in front of me," she wrote on the fundraising page set up to raise money.
"The dreams of watching my children growing up, walking down the aisle one day becoming a gran all the beautiful things we dream of as a parent," she continued. "Within in twenty four hours my life came crashing down in front of me."

"Alone in hospital in the middle of the pandemic not being able to see my family or friends dealing with the fact I'm dying was heartbreaking," the devastated mum continued. "The thought of having to tell my beautiful children I'm terminally [ill] was literally breaking my heart."
The mum-of-four was later diagnosed with COVID-19, which prompted her to create the TikTok account, terrified she may pass away sooner than she thought.

The account, which Pentland has been using to document her cancer treatment and so her children have a way to remember her, has almost 50,000 followers.
The videos Pentland gives updates on how she's feeling, day-today activities and answers questions from followers.
She also linked the fundraising page, where she hopes to raise money for funeral and medical cost saying that "every penny helps."
"It's unbelievably gruelling, the chemo absolutely floors me," Pentland told The Chronicle Live.
"But I'm doing it for my kids - they could chop all my limbs off if it meant I could be there for my kids for longer."
