Help My Mom Medical expenses

My mom was recently diagnosed with Carcinoma cancer. The doctors have said surgery is not an option at this time. We are hoping that her body will respond well to radiation chemotherapy. The doctors are unsure if they can completely get rid of the cancer.  Her treatment will be five days a week for six weeks. My sister and I live in two different states. My stepfather is caring for my mom. He is not able to take off six weeks of work . These funds will help my mom and stepdad during her radiation treatment for rent, utilities, groceries/food delivery , gas, dog walkers/boarding, and even medical expenses. While my stepdad is not able to work. The hospital is a little over an hour away so they will be in a hotel during her treatments. Please do not notify my mom about this post. She is a very private person. Me and my sister are not in a financial position to help her financially the way we want to.
