Well, I have contemplated it. I remember feeling a penetrating, cutting, undying loneliness, pain, and misery. My misery wasn't economical, nor health related, it was social, being made a pariah and after a while pretty much accepting being one is hard on your psyche, you tend to lose sight of things.
I didn't make my death wish a daily routine, it was more like a moment that felt like 12 hours, where I was gazing through nothingness and just thinking about it, about not being there, about leaving all behind, about not feeling anything else, after all "anything else" just meant shit.
But, It got to a point were I just didn't care anymore, I think that caring burdens you, it is healthy to care, but only to care a lot about a few things. I didn't care for my own suffering, or for anyone else's for that matter, just of a select few. I guess I closed myself to many external motivations.
I also don't care a whole lot for other human beings, I grew weary of them, of us, at least we haven't managed to kill all other species, dogs are around, dogs are nice. However, I still get enraged by people, by little things, by their apparent insensitivities, but at the end of the day they'll be gone, won't bother me any longer. I guess I'm a cold selfish cunt, but that's how I learned to handle my "blue condition"
