Hi ousier 

I really have no advice but I couldn't not read this and not try to offer some words of comfort, I'm so sorry that your  having to go through this and with the pandemic it makes it doubly hard. My mum was diagnosed with bowel cancer just before the first lockdown and looking back now I can see how the cancer had really started to ravage her body, she was literally skin and bones and she hid alot from us as she didn't want us to worry, thankfully my mum was dealt with really quickly. She had her operation and they discovered the cancer was a really slow growing tumour and it was only in her small bowel so they were able to remove it all. I can't imagine the pain you must be going through, my world seemed to stand still the moment my mum told me she had cancer so to be in your shoes now I can't even imagine it. Cherish the time you have left with your dad, let him no how much he is loved, saver every minute you have with him, make some memories as these will last a lifetime, and just be there for him
