Since you are about to die, and as I understand it, you have nothing to lose, try to do two things: 1) start a conversation with any random person of your choice, sitting on a bench or waiting for something, so that he is ready for a long dialogue, and talk to him about topics that interest you - only rationally, as etiquette requires. That's it, spontaneously. It may not work the first time, but the attempt should end in success.
2) Before preparing for suicide, or before committing it, write down and read this carefully: "Lord! Your name is Love: do not reject me, the lost one! Your name is Strength: support me, exhausted and falling! Your name is Light: enlighten my soul, darkened by worldly passions! Your name is Peace: calm my restless soul! Your name is Mercy: do not cease to have mercy on me"
I don't think it matters to you what you do if you're going to die, so here's my recommendation.
