My Wife is dying at 40 - she was diagnosed with stage 4 liver cancer in October. Struggling to keep it together and to be strong for our 10 year old boy

My Wife was diagnosed with Stage 4 Liver cancer back in October and ever since she has been in and out of hospital. We have a wonderful 10yr old boy who i am trying to keep it together for but really struggling without her in the house at the moment. I know i need to be strong for my boy and i am doing my best but this time of year is making so hard. I just hope she can be home for what will be our last Christmas as a family
