My mum has just been diagnosed with breast cancer which has spread to her bones. She is stage 4 on diagnosis and is already in alot of pain and very tired. 

Everything has happened so quickly and I am so worried that I won't have enough time with her. I am 30, she is 54 and I am trying to be strong for her. She and my dad are divorced so he isn't and won't be involved and my brother is in a difficult place himself. I have been looking at statistics although I know that a number of people can live for a long time with this, I have the most awful sense that our time is limited and I am struggling to believe that all this is happening and there's nothing I can do
