Are family members just cold these days?

I am having a hysterectomy and may have to have an abdominal if my uterine cancer has spread to the lympathics. My sisters were worried and wanted to come and help me. I called and told them when my surgery is and now they can't make it because they can't afford it. They were getting discount tickets! I have noone to help me now. What kind of people are in the world these days who can't even help their own relative? Thankfully I have church ladies to help!
