I am devastated by this news

I just received a phone call from my mom.  A young lady the age of my sister, who was friends with my sister throughout school and with whom I worked at summer camps for years, has been diagnosed with metastatic breast cancer.  She'd had clean scans for years, but they just found it in her spine.  Her three children are elementary age, and she is one of the nicest individuals I've ever met...and I've known her since she was only four or five.  I know that there is currently no cure for something like this, and while she may have years to live, it isn't decades, and her children are so young...and so is she.  My heart is broken and I am devastated by this news.  I'm praying for a miracle.
