Help covering my parents monthly bills

Hello, I am DJ Middletent and I am fundraising for my parents to cover their monthly bills for November and December. Due to an infection in my mothers knee she needed to have surgery to remove the infection and is awaiting a second knee replacement. The past 9 weeks she’s been in the hospital and is finally home but she is still immobilized. She has been working for the school for 40 years and used up all her leave which led to her not getting a check. She has not been cleared to go back to work as she cannot out weight on her leg. My father was recently laid off from the tribe so that leaves my mother with the only income in their house. Her next appointment is Dec 7 to see if the infection has gone away and if she could get her knee replaced so she could head back to work. Please help with anything you could my family would greatly appreciate it.
