I'm so sorry that your family are having all these troubles, I can understand you asking the question why? I'm sure you haven't done anything to warrant all this misery. Your whole family sound like very strong people, they must be, because your Dad and Sister are recovering and you have made it through your breast cancer. Life throws some crappy things our way, I lost my mother to BC when I was 15, my sister had a mestectomy 17 years ago and is still going strong to this day. I also lost 3 aunts and grandma to BC as well. As you said, stay positive, support your Mum and together you can throw a curveball back at the universe. I wish you, your Mum and your whole family all the best for the 21st Jan and beyond, sending you big hugs for this tough time,
