Cancer Can't Always Win

My mother was diagnosed with stage 4 cancer in March. She's never been sick. Its such a shock for all of us. She has had to quite her job so has lost income. I'm unable to work due to taking care of her. We have 2 teenage boys in the house as well. We are in need of help getting back in forth to her chemo an overnight stays. Its a Two an a half hour trip we make 2 every other week. Any help is appreciated.
