My husband has been having cancer treatment for coming 5 years.  Began as colorectal then peritoneal and now in the pleura of left lung.     He’s had two massive surgeries and come back fighting but at 84 the chemo I can see is taking its toll.  
he has a couple of days in the cycle when he’s hardly awake, can’t eat and is sometimes sick. But he continues to fight.   We know he’s now terminal but I say we’re ALL terminal.     
I watch him when he’s sleeping and break my heart.
