I don't want to see my ill dad
Well first I would like to know why he is ill in the first place?
He smoked since I was born. When I was 7 years old my dad came down with lung cancer
It's wrong to abandon your sick dad. You should be there for him, even if the cancer is his fault.
I'm fine with cancer, I don't want to talk about it.
I understand that you have finally come to the terms with his consequences, but he is still your family and he needs as much support and goodbyes as he can take in his final moments. If not for him, why not be there for the rest of your family?
