Dad recently diagnosed with St4 pancreatic cancer

Hi, I’m new to this forum and would honestly just like some comforting words or someone going through a similar situation. About a month ago my dad was diagnosed with pancreatic cancer which turned out to be stage 4, he’s starting his first round of chemo today which is in all, to see what quality of life he can have left. I’m only 20 and my dad has been a big part of my life and I’m not even able to comprehend losing him, is anyone going through something similar?
