In my case it's not "depression" but rather just having awareness of how truly undesirable existence is, I cannot stand when people act like others are ill for wanting to permanently be relieved from having the ability to suffer.
Not wanting to suffer an isn't an "illness", no existence is the problem instead and under no circumstances would I ever wish to exist in this evil, repulsive world where there is literally no limit as to how torturous existing can get.
Only non-existence is ideal to me, I only wish for the peace of an dreamless, eternal sleep, in my case suicide is all that feels rational as I don't want to suffer in any way and in this world there is endless suffering, I have no interest in something as meaningless, cruel and futile as existence.
