Hi all, my dad was recently diagnosed with lung cancer after months of treatment for an abscess. By the time they realised they were wrong it was too late. He's had a nasty infection and they said if they could get that under control they could try radiotherapy to slow the growth. Eventually they started the radiotherapy but quickly realised it has no affect. The cancer is growing so fast his blood vessels can't keep up. It's spread and this week we found out that nothing can help him. They say it could be days or possibly weeks but not months. 
Today Iv said what I needed to say to him, I know he's going to be gone soon but I just feel so numb, not just to my dads situation but to life. I just feel like I'm not part of my day? I am grieving for certain he's just always been there and he won't be soon. I do understand the process but I can't seem to get myself to catch up. Does anyone have any advice? I need to feel whole again to support my mum and sisters properly. Thank you
