I’m sorry you are going through this. Can’t imagine how hard it must feel, but I hope things will turn out for the best.

Thank you, bro

I'm sorry to hear about your dad. I'm not sure if this will help, but personally, I'm the sort of person who finds education and knowledge about something/anything comforting... maybe it'll help you/your dad too.

Hospice Nurse Julie is also on Youtube in case you prefer a different kind of medium. This might help: https://www.youtube.com/watch?v=jrxAE_RJ0qM

P/S: I'd recommend against immediately getting into the deep end and starting with the vids marked "real footage". It can be really disturbing for some.

That said, there's one thing that really resonated with me when it comes to death, and funnily enough, another hospice nurse left it as a comment under one of her vids:

death is a transition.

The same way that babies are born.. they’re warm and comfy in the uterus- what they’ve always known. When the amniotic fluid drains away and labor begins, one may think it’s the end. When they begin the uncomfortable journey down the birth canal, one may think it’s the end, as they’re leaving their home they’ve had for the past 9 months. But then there’s a transition into the world. Babies don’t know what happens after birth, the same as we don’t know what happens after death… but equally it could be wonderful as being born.

Hope this helps!

I pray he pulls through. Talk to him tell him sometimes being brave is only thing to do fight it out or go all out trying. leave rest to God. Tell him you have his back. Nothing motivates parents more.

I hope that things will be better for you, I'm sorry to hear about your dad.
Lost my Grandma to cancer and 5+ years of dementia recently so I can feel your pain somewhat at least.

Hugs.
