I’m so sorry to hear this mate, I’m going through a very similar thing with my old man at the moment they discovered a 15cm tumour on his kidney last week. I’ve never wanted to gamble more and just escape, I’ve been trying to focus on other shit and keep my mind busy although drinking has helped. I’ve also taken all my money out in cash so it’s not such a temptation I’d recommend the same mate, it’s one of those times when you just have to press on and look for any silver linings and try to keep a smile on got your dad,
wishing him a good result mate x
