I think if you're doing it "impulsively" then clearly you are not ready. If you were ready then you would take your time planning it out as to minimize mistakes. Being impulsive just means you're running away from something, in this instance life, hoping that death will bring you peace. That's the difference between those who are just wishing they would die, constantly venting on this site about possibly doing it, and those who are beyond that, who take the time to analyze their life circumstances and come to a decision it has to be done. If you're a mature and serious person once you make that decision it's basically just getting the supplies and timing right, meaning finding a hotel,, waiting for people to be out of the house, cleaning up finances, etc. I'm not saying people won't second guess themselves and it's even ok if they begin the process and turn back. But In my opinion being impulsive just means you're still deep down not truly ready, youre just trying to escape the current pain.... then again a very few really ever are ready, probably mostly old or very sick people who have given it every try and there's nothing left. Takes a lot of will and strength to overcome the survival instinct.
