Sending positive thoughts you way, man.
My father-in-law passed from liver cancer. Same day a buddy of mine passed from cancer as well. I got the call around 10am for the buddy, a little after 6pm for the father-in-law.
We knew they were both going to pass and thought that knowing that it was coming would help when the time actually came.
In a way it did but didn't. The finality of it all starts to hit. Don't let it get to you. There's no more suffering.
Keep your head up.
