Hi, I've posted here once before and found it very calming and useful. Hoping for a similar result this time :)

So my dad was diagnosed around 3 months ago with stage 4 bowel cancer and it is aggressive, he's had a few issues recently with bowel blockages but he's been given meds to help ease this. The issue I'm finding really hard to cope with now (and my mum and sister) is the sudden deterioration in his physical self and his mental wellbeing. He's always been a very clever man and has been the perfect dad his entire life, worked hard and saved money so that we (his family) would always be financially secure if he ever passed away. To see him quickly start to deteriorate and become so small and vulnerable is extremely difficult to comprehend, today I felt sadness when I looked him in the eye to talk. My poor mum is living this nightmare each and every day and I try my best to keep her positive but I'm now struggling to do this for her. Please if anyone has been through this struggle and you know how it feels, any advice would be so appreciated.
