I always try to convince myself there is no God, there is no one watching over this planet, we are all on our own. Despite not believing that there is someone who is 'looking out for us' as human beings, I do believe there is a higher authority out there watching everything unfold and maybe knowing when the end of it for all of us actually is.
Saying that, my conflicting views on God leave me to wonder whether whoever or whatever meets me after death will have something terrible planned out for me, because yes, I do believe suicide is a bad thing, and yes I agree with the phrase about how you're not ending your pain, you're just transferring it to another person. I certainly do believe in karma - I've had too many experiences of it in my lifetime to believe otherwise, whether I be on the good or the bad receiving end of it.
But then karma makes me wonder whether it's actually me who will be receiving it. It's a common idea to believe as early repliers have mentioned that we are mind-wiped and come back to Earth as another person. Maybe in that case the pain we will receive in the next life might be far worse than what we deal with now as suicidal people. Or maybe we will continue our existence somewhere else but receive, well, absolute hell for what we've done.
Or maybe, if we're lucky, the universe will feel empathy for us knowing that we were simply in pain.
At the end of the day, I think truly suicidal people aren't afraid of what comes next because we are just craving an escape from the life we live now. Illogical, I know. Whether it be a continuation of our existence somewhere else, or we are reincarnated, or nothing happens at all (which I highly doubt, but maybe that's just a human's narcissism) I'm not really afraid. I think the fear we all have is actually physically committing the act, we're afraid of being in pain and someone spotting us and just what message and physical state of us we leave behind on Earth (which isn't really fear, just human instinct). At least that's the case for me.
