I also relate. Im a social parasite, unable to be productive. Everytime i've got something good in my life like friendly people / job / girlfirend - i always subconsciously did things to ruin that and then feel like i'm a victim of these people meanness. So im just sitting now on my chair, doing nothing, being completly alone, hated by dozens of people, watching as everything around colapses and living with memories of all of these times when i actually had a chance, but blew it.
I very much deserve to die, because that is the natural order of things - weak and failures needs to die - this is how nature makes species capable to survive - weak dies and strong reproduces, but because all of that technological and social progress we (humanity) achieved a position that allows us to keep weak people alive and this is a reason why people like me are still capable to be there, breath and eat resourcess that could've been used by other people that are actually productive.
I know i should die, but i can't force myself to actually do it. That's the irony of weakness - you are too weak to have a right to live, but you are also too weak to stop living, because that would paradoxically require an actuall strength to "pull the trigger", which obviously im not even close to have.
