So I know I want to be done, I just can’t go on anymore, but I’ve been stuck on the best way to go through with it.
First thought was just a knife stab to the chest. But that’d be very painful, and to increase likelihood of success is have to remove the knife post-stab, which I just don’t know how that would go down.
Then I thought about gas. Helium or ********. Wearing one of the nose/mouth masks carpenters wear, sticking a tube in it with duct tape eliminating gaps with the hose attached to a tank of helium/********.
Would this work?

 Life is full of unexpected hardship. Have you ever run out of gas before, and been forced to walk to the gas station? Well, it’s rough. It will take almost a minute before anyone stops to pick you up.
