I'm also not sure, but there is a lot of well poisoning about that. Usually, if someone physically healthy decides that (s)he doesn't want to live any more, we automatically declare that person mentally ill (even if no chemical imbalance seems to be present). It's implicitly stated that ending one's life is a decision that can't be taken rationally (unless a terminal physical illness is present). I find that quite disturbing.
