Unless you kill yourself, because you know, that happens a lot in untreated mental illness

Or even more “minor” stuff like not taking care of your own health, pushing away everyone you know and love, or even maybe want them to hate you so that they won’t get hurt when you do finally do something

You are downplaying mental illness, whether you admit to it or not. Our brain is the core of our being, why do you not take it as seriously as the rest of our body?
