In my case suicide is certainly all that feels rational, for me ceasing to exist would be the most beautiful release from the evil that is existence. My wish to die is a result of becoming aware of how truly undesirable existence is and how existing is just pointless suffering that is best avoided no matter what.
I have no interest in being trapped in this existence for decades on end that I never wished for in the first place that can potentially get so torturous way beyond how anyone can imagine it to, just to decay and die slowly and painfully from old age.
I'd always prefer to not exist than to have the ability to suffer in this meaningless existence, I only wish for true peace, not the futile and dreadful burden of existing as a human, I don't want to suffer in any way and in existence there is endless potential for suffering.
I find it tragic how life exists at all and I see existence itself as the true problem, more than anything I wish I never existed at all, procreation is such extreme cruelty.
