So if you want to do it painlessly, overdose on insulin. You’ll (literally) go into a sugar coma and never wake up. Won’t feel a thing, even less painful than overdosing on pills.

If you want to an hero, I’d recommend activating a wood chipper in a public park, then jumping in. It’ll hurt like hell, but you’ll be famous for the horrible shock you caused to the children. Pop some pills beforehand if you don’t want too much pain, but the screams from the chipper would make you a winrar.

Now, corpse disposal. Your best bet would be middle of nowhere. Depending on your location, you have several choices. You can run out to a ditch and die for starters. You might be able to get a friend to carefully bury your body so they’re not suspected of anything and it looks like some ****ed up murder. Here in Oregon though, we have Mount Hood. People go up there every year, and bodies are rarely found. By the time someone finds your body, any evidence will have decayed, and it would look like hypothermia or frostbite.

Obviously corpse disposal doesn’t apply if you go with a wood chipper.

Could get a bunch of illegal fireworks, take the powder out, take a hollow vest, fill it with the powder, then light it on fire while wearing it. Might even be more painful than the wood chipper.
