Please help us to extend my mom’s life

Hello people! We need your help! My mom is dialysis patient for more than 3 years now. She has diabetes and suffering from stroke. We've been in and out for hospital these past few months because of her complication with heart, lungs and kidney. We're seeking help because her kidney is in bad condition. It is infected by bacteria and it caused her high fever, lack of appetite and pain on her left tummy
