I would love to believe that this is some kind of a cry for help but given the length, structure and how well this is written lacking any kind of actual emotions that would translate through your words, I have to say this just seems like attention seeking.
Literally every second someone dies and another person is born. You have one chance at life. As far as we know there is nothing else and hedging your bets on someone's word that there is without evidence is just mental. Secondly, life has not purpose and no meaning. That job is up to you. You give it meaning and you give it purpose. But if you decide to end it, just end it and don't go crying about. If you are conflicted, then seek help. But going on reddit, I mean WTF are you after here?
