Please help fund our mom's surgery

Firstly, thank you for visiting this page.

My mother has needed surgery for over four years now. Her right hip bone is degraded and requires complete replacement. She visited the doctor for an assessment last year, 2019, and was recommended to get the surgery done. She was also recommended to do physiotherapy but attended only one class due to financial constraints. Because of these financial difficulties, my mother, not wanting to pressure us, said she felt fine and did not need to do the surgery. Fast-forward a year, and a few months later, we realize that we cannot continue with this plan of ignoring the problem. About a week ago, my mother said she has been feeling severe pain in her affected leg for a few days, usually at nighttime, but did not want to bother us with this new development. She could not bear it anymore, so she came out and told us. She needs to do surgery as soon as we can afford to buy the required materials and to pay the surgeon. These are the most necessary cost, which we are asking for assistance. We really would like this to be done as soon as possible as we fear she may develop complications.

I am a master's student in Canada. I do receive a stipend, but I have been using this money on my expenses, being the sole supporter of myself. I have a younger brother in whose university studies I am funding, leaving me no room to save. I have sisters, but they too are not able to help financially. My father suffered a stroke some 10 years ago that left him completely vulnerable and in need of care. He is now in his late 70s and has developing dementia so he is not in a position to provide support either. And so, we are reaching out to you. We greatly appreciate anything that you can give to us. Thanks very much in advance.
