Grandmother's Breast Cancer treatment

Talofa, greetings from my beloved culture, my name is Ojani Oloapu, I am 15 years old and I'm  writing this request on the behalf of my family and specifically to my grandmother who is unfortunately in a horrible condition. It is an extremely melancholic period of our lives, conjuring this idea of her ultimately lying on her deathbed sickens us and also alluding us to question whether we're to blame. The quote stated from the lead character of Forrest Gump (played by Tom Hanks) says “My mom always said life was like a box of chocolates. You never know what you're gonna get.” is irrefutable and it is an accurate dictation of the protracted nature of our lives and how it can be simultaneously malleable or stiff depending on the circumstances - i.e destiny/fate or human action. What exactly happened? My grandma is 63 and was recently diagnosed with breast cancer. She lives in Samoa but rumour has it that every female who had surgery in Samoa died immediately after. So with the support of my mother, father and uncle they were able fly her to a better country, New Zealand. Aforementioned, life is really unpredictable, in saying that everything went well, she landed safely  at New Zealand and is staying with my uncle (same uncle who assisted to pay for the flight).  Majority of the plan went successfully, until couple of days ago we were informed that we have to pay $10000 before the 11th of January, 2019 in order for her to undertake the surgery in New Zealand, if we don't pay it then she has to go back to Samoa. 

Since she isn't a New Zealand citizen or resident, she isn't eligible for funding's by the government so my mother and uncle are her only two children that aren't in Samoa that can provide her with support. However, they also have children to feed and take care of so splitting $10000 each to pay is close to impossible. So we will take any donations before the 11th of January, 2019.
