JoAnn's help fund

This is my mother, JoAnn Purnell, she was recently diagnosed with multiple myeloma, a bone and blood cancer, in late Stage 3. It has been a very rough almost 2 months of ups and downs, Duke's ER didn't even catch it, only thing that was said to my mother was, "Well, you're in kidney failure so we are moving you to Lutheran in Fort Wayne." 3 weeks later the rent is now due on her apartment and we have no way of coming up with this money. If things go according to plan, she has roughly 2-3 weeks of rehabilitation , so she can actually do certain things on her own, and then she will be sent home, my sister and I NEED to ensure she has a home to come to, so I am asking the people that know and love my momma, could you please help us out with this situation?
