Perfectly happy until adolescence, but couldn't, either through laziness or cowardice, master the developmental demands of independence and drifted into helplessness, disorganization and listless neurosis. I had enough interest in the world to acquire an education, but by the final year of University I knew was doomed.
Have been passively suicidal and indifferent to living since that point, so around 14 years. Active suicidality is a more recent development in the last three years, following a psychotic crisis, pharmaceutical mismanagement of said crisis and unfiltered exposure to pessimism/anti-natalism.
I'd be tempted to loiter in the hope of seeing how the recent geopolitical chaos will resolve itself, but at this point I honestly don't have the patience.
