"I always felt like it was going to happen."
Doctors found a staggering 13 spots of cancer in his stomach. The whole organ had to go or the cancer would keep on spreading.
On September 14, last year, Walker lay on the surgery table as doctors removed his stomach.
Now his oesophagus is attached to his small intestine, which operates as a small stomach. "Eventually it will stretch β within six months, I will be eating normally again, everything should be functioning."
The surgery may have got rid of the nasty cancer, but his battle was far from over.
"The cancer was the easiest part. The deadliest, but the easiest," he says.
He's since had a collapsed lung, his appendix removed and emergency surgery for his gallbladder, among other struggles.
Walker opened up about his mental health struggles over the years: "Throughout my life, I've wanted to die so many times. I tried to commit suicide when I was a kid and even as an adult, things get too overwhelming. That's why I like talking about that stuff β people think it just ends when you get successful, but it just gets worse."
Now, the kid who'd wanted to kill himself just wanted to live.
And so he kept fighting. When doctors said he needed gallbladder surgery, he told then: "no, tonight I have a dinner with the Prime Minister".
And dine with the Prime Minister he did.
On social media, people wondered why Walker looked so skinny. No one could imagine the hell he was going through.
Walker has dropped from 102kg to just 67kg. He says he can't put weight on, all he can work on is him not losing any more.
He is also struggling to accept his new body. "I feel like a little kid. I'm still getting used to my body... It sounds stupid, but I hate being a pussy."
But through all that hell, he wants his fans to know one thing: he is here and he is fine. He's not the Stan he used to be - that one did die - but he's a new one, who's found the joy in life again. And maybe, he wonders, he had to go through all that pain to find that joy he'd missed.
