Burial, Funeral and Bills Left

My mom has stage 4 breast cancer and is in the hospital for the remainder of her time here with us. She has a collapsed lung and is on the maximum amount of oxygen they can give her, her body is filling with fluids and she isn't doing good at all. I don't like asking for help but me and my 17 year old brother are responsible for paying for her funeral and Bills that she owes and we just need some help.
