Patty when my mom got sick I lived 200 miles away. I have a brother that lived 10 miles. his wife did not work. she would not go help my mom at all. guess who did? me. I know what you are going thru and it stinks. not to defend your sister but some people can't handle caring for the sick or more like won't so they make excuses. We are all here for you. if you want to know things about this please feel free to pm me. my mom had the same cancer. you are not alone hon.
