Fund for My Mom Surgeries and School Fee

Recently, my moms knees has been hurting so bad, till the point she can't even walk properly. It has been going on for quite some time, years i believe, my mom hid the pain from me as i had to focus in school + the surgery fees are HUGE, about $22k, we're not from a rich family nor do i have my father as a support, all my finances comes from me and my mom. Now that my mom is out and she can't work due to her knee issues and covid is preventing me from working. I have 0 source of income and surgery will put a hole in our finances. Doctors found out that her knee requires immediate surgery and it must be replaced or else the pain gets worst and she might not be able to walk anymore, and also they discover a tumor in my mom's intestines and as of now i do not know what the tumor is exactly but it is definitely affecting my mom and things just gets worst as time goes and i want to be prepared for the worst with this gofundme's funds. My school fees cost around $2k per semester and it'll be hard to get that kind of money while studying and working part time. But i want to prioritise the money that can be raised towards my mom's surgeries, and i will be forever grateful and i thank all who donates even if its just a dollar, it will be helpful.
