Very sorry to hear about your cancer.  
You mention preparing for the inevitable, but that may not be the case. Unless they have already handed you a terminal diagnosis, of course.
I'm not a medic. But I know that in some cases, and I hope you are one of them, colon cancer, spread to liver, can still be treated with curative intent. So my advice is to get as much information as possible, learn about the different options, then decide what you want to do.
There are known centres of excellence in the UK for colon cancer. Do not hesitate to identify them, and seek a second opinion, if you are unsure of anything.
Wishing you all the best. x Harry

You will get through this. You will but your mindset is so important. My dad is going through this now - and you need strong people around you and to set your sights on the goal to get better. We have some of the best health care in the world here. Don’t “prepare for the inevitable” just yet please. Are you on a low fibre diet?

Hello Samxox thanks so much for your response. I have started and on my 3rd round of chemo it has been tough but as you said a strong mindset.  I have good days and bad days.  I did speak to a dietitian which was helpful.  I'm not on a low fibre diet but I normally avoid high fiber foods as my tummy can't cope with it.  I do eat beans and pulses with skin but avoid fruit skin.  Wishing your dad the very best.  And thanks so much for your response.
