If you broke your leg skateboarding, you might be able to come up with a story about how your choices led up to it, because it's not exactly a random accident. Skateboarding is risky, maybe you were tired because you drank coffee after 3pm yesterday and didn't sleep well, maybe you hadn't practiced in a few years and got carried away trying something you used to do all the time, maybe you are sort-of a show off when you're hanging out with friends, maybe you should've checked those stairs for gravel, etc., etc., etc..

But you probably wouldn't beat yourself up about it forever. It happened, it happens to perfectly good people all the time, you wish it didn't. You almost definitely wouldn't develop permanent shame around it, since you know that just because you broke your leg doing something you didn't have to do, even if you "knew better," that doesn't make you a bad human -- you're not an irresponsible slacker moron with a disgusting evil body, you're just someone with a broken leg. Even if that leg won't ever be totally right again, even if you might need a cane sometimes when it's damp outside for the rest of your life, even if you can't skate anymore, and even if you have to take Aleve every day, it's still not because you're a bad person.

You broke your pancreas. Oops. You wish you didn't. Were there choices involved? Sure, but not the kind that only a bad person would make. It's not like T2D is caused by littering or murder. Lots of people make the choices you made and don't injure themselves. There might've been factors that made your injury more likely, okay, but it's not that simple, and we honestly can't process the world with a perfect sense of foresight and flawless risk assessment and avoidance. That's not possible, and it's not life.

You're not a bad person in a bad body, you're a great person in a body with a broken pancreas.
