I'm sorry that you thought this game was about suicide. It's not.
This is a game about not giving in to peer pressure, where the computer is pressuring you into doing something dangerous (drinking bleach) and you must continue to resist. This is more obvious in the Genera version where instead of answering yes or no, you choose between the options "Drink" and "Refuse", where Refuse obviously implies that this isn't something that you have decided to do on your own. You aren't expected to ever drink the bleach. You win when you realize the game is futile and quit.
