I've had experiences with friends where they tell me they're all suicidal and shit, but you know they don't mean it and are just looking for some attention but you can't tell them that or ignore them, because you could be wrong.
Suicide is silly. If you actually believe that there's no other way out of it, no amount of talking to someone would actually help. With that being said, goodbye to those who think that's the only option. I don't know what else there is to say to them.
