girlfriend just been told it's terminal

Hi there, my absolute world has been shattered after being told my gorgeous girlfriend who's only 22 years old been diagnosed with a rare cancer and been told she has   Months to live. She has a very aggressive cancer and is on  a lot of pain killer etc were just hoping to get her home to.   Live  out her last days with us. So my question is does   Anybody know of people who have skipped chemo? We all    Know it's not going to end very soon so I'm just thinking   Is it really necessary to put her through so much pain to just  eventually die? I can't bare to see her go through it after   Hearing all the stories? Is  thanks
