I bet your wife is gonna do great. I used to hate going to the doctor and maybe hearing about something new. Now I'm like "What's the recon report, let's hunt it down and kill it."
In an odd way I am grateful to cancer. Before it, I kind of shuffled along doing stuff I didn't like, because that's what we do. I didn't take a stab at things I really wanted to do that weren't "practical." Post-cancer, I had the power to say "Fuck that shit, I ain't doin' it, I got cancer," and then I was a free man. Oddly started making more $ doing the non-practical stuff. Funny world.
The thing is, things that seem horrible when you first imagine them, when they land on you, you just deal with it. What helped me at first was seeing all the old-ass Stage 4 patients at treatment, some of them had been plugging along for 20-30 years with primitive treatments, just putting one foot in front of the other. Now we've got good stuff, and we'll get better stuff tomorrow and the next day.
Give her a hug. She's gonna do great.
