Hey - I know exactly how you feel as I'm living that too. Found out beginning of year my dad had lung cancer and when he was doing chemo & radiotherapy he seemed so positive and strong. But now we found it didn't do anything and its gone to his brain also. My dad has slipped into depression and is in a lot of pain from one of his brain lesions so is on lots of morphine. This has changed him completely and it's heartbreaking to watch. The one thing I would say to cherish is the fact you can be there with him even its to hold his hand. I cannot as I live in Sydney Australia and my partner is 8 months pregnant with our first child. She has no family to support her here so if I come to UK I may not be able to return due to severe travel restrictions. 
its incredibly hard for you to watch this deterioration but at least you should take comfort that you are by his side every step of the way and he will know that. Give him a hige hug if you can as that is all I keep dreaming of having the chance to do

Hey Adam ️
 

Thank you for responding back to me, and I would just like to say I am so sorry to hear about your situation. I can't even begin to imagine how hard that is for you. That must be so difficult knowing that you can't come to the U.K. due to restrictions, however I am sure that your dad would want you to be there with your wife to see the birth of your first child. It doesn't matter where you are, your dad will always be with you.

I completely agree with you in regards to the morphine completely changing the person you love. My dad has been in a lot of pain with his spine and shoulders due to where the cancerous lesions are growing, and he has been given lots and lots of pain relief. I find relief knowing that my dad isn't in pain, however it is horrible to see him so delusional and 'out of it' when he has the medication. It is the pain that my dad is going through that is been the hardest to see, as you can do nothing but stand and watch. It is so cruel. 
 

I will continue to try and make the most out of every second with my dad, even though knowing what is around the corner makes it all the more difficult to truly 'appreciate' that time, as we all feel robbed of our time with him. 
 

My thoughts are with you and your family x
