My bed.
I was initially going to do it in public; there's a pedo at my local mall I wanted to beat up right before I kicked the can, but I don't have access to anything that will kill me quickly after. I'd go to prison and have to hope it wouldn't take the inmates too long to stab me to death.
I was thinking of driving my motorbike without a helmet and becoming nothing more than a bloodstain on a wall, but that would give a lot of innocent people ptsd. And since my parents hate the fact that I own one, they'd blame themselves for letting me drive it instead of getting me a car as a safer option, like they'd wanted.
I'd also hate for my mom to see my body mangled up or unrecognizable or gory in any way, so I basically ruled out all of the most violent ones.
That leaves hanging and overdose. If I do it outside of the home, my mom will be worried sick about why I didn't get home that night. She doesn't need built up anxiety before the devastation. Losing a child is too much on its own.
I don't even want her seeing the rope around my neck. She'll never get that image out of her head.
So passing in my bed in my sleep it is.
