Preferring to not exist doesn't automatically mean that the individual is "ill" for wanting so, I don't understand those who hold that view and force it onto everybody. In my case existence itself is the problem, I have no interest in something so evil as existence, I find it so tragic how humans continue to impose it in the first place even know there is literally endless potential for suffering and torment in this hellish reality. My wish to die is simply a result of becoming aware of how truly undesirable existence is, I don't wish to suffer in this disgusting world, Instead I only want the true peace of non-existence.
If "better" means wanting to suffer just to risk experiencing way worse suffering then under no circumstances would I ever want that, existence truly is such an abomination which is why only wanting to not exist makes sense to me personally.
And yes I certainly have lots of dread for what lies ahead, it's horrifying to me how this existence could potentially go on for decades as we truly do exist in hell. I really despise how we cannot all just have the option to die in peace, it's evil how humans make suicide basically illegal even know existence truly is so futile and harmful with no limit as to how much agony one can feel.
