suicide ( in general )

Not all people I encountered understand, why would you in the first place want to kill yourself. Like why? Normal people won't. It was just ridiculous. You're just too weak. Everybody is suffering ( probably much worse than you, and yet they are still struggling to live )
So the limit of advice they would say are probably "hang on. it will get better soon"
But what do you, really thought about it? When someone close to you said that they are depressive or thinking about suicides, are there any alternative to say other than "ït will get better?" ( it does sound like a bullshit to depressive people tbh )
