there are ways to bypass your primal instincts of survival. hanging is unpleasant because of suffocation, but if you just clamp your carotid arteries you can still breathe. less than a minute to unconsciousness, a few minutes more & then it's bye bye.  try it yourself (in a capacity where i am not telling you to kys)  find the spot where your jaw meets your neck, just behind your trachea and press on it with your fingers for a while. you'll know you've found the sweet spot because your pulse will be very strong there. just press on it with medium force and you will find out how soon and painlessly your exit from this world can be. you will experience some head rush symptoms after relieving the pressure though so be warned.  so long as you can still breathe you will likely not enter a state of panic. cutting the circulation to your grey matter will likely be a way to bypass your survival instincts. you can either use a wide clamp sold at hardware stores, or if you have it in you and want to ensure a good bye, use a box cutter on both sides to do the job. that will leave a mess, but even if you call emergency services before hand to give them the courtesy of a body pick up request, they likely won't have the time to stitch you up and pump you full of blood from someone else. if you try pills you might be 'saved' only to live with liver damage, and if you try hanging you might be cut down and have to live with brain damage. go for the neck.  just be damned sure to follow through especially if you call ems, don't let them keep you on the phone. give them the address, tell them the door is unlocked and there is no danger to attending officers, then hang up and do the deed.  also, make sure to liquidate your assets and send them to your mum beforehand to disperse among your siblings and try to rehome any pets you have.
