This was always a big concern of mine as well.
Recently I have become agnostic (for those out of the know, it basically means I don't believe in God necessarily but I also am not an atheist because it is impossible to prove one way or the other of "His" existance). Agnosticism has many subcategories such as agnostic atheist, and although I wouldn't categorize myself as that, I am definitely leaning more and more towards the whole he doesn't really exist thing. Mainly because of my knowledge of evolution, science, the way the world works, and pure freaking logic.
Annnyywayyyy. I grew up believing general Christian principles and even though I don't believe in Heaven and Hell, the thought that it in fact MAY possibly exist definitely is a huge factor in not committing suicide. It sucks becuase as another person mentioned, it's so hard to get rid of an idea like this when you've grown up with it.
It would be so amazingly nice to just say, hey... if I die, I'll just be a corpse lying in the dirt somewhere. And that will be the end of my consciousness as my brain is no longer functioning. I will feel nothing. Everything will be over. I won't have to deal with day to day shit anymore. Nothing. Yeah... I might make some other people that love me sad, which I would feel pretty bad about becuase I love them too. BUT... I would be dead! So I wouldn't feel anything. That's such a comforting thought. But alas, there is no way to know for certain one way or the other if God and all that hoo-ah exists.
I just have a problem believing that we would go to Hell for killing ourselves for a few reasons. It's like the whole we're supposed to believe in God through blind faith instead of physical proof because that proves we TRULY love him. Then why did he make so many of us curious, not trusting, yadda yadda... basically making us work AGAINST our basic nature? No. Religious folks will say, well that's the point, to make you WORK to love him, so you're not just believing it because you know it exists, but you're actively loving him and seeking him out. Well what the fuck? Did I ask to be born and have to WORK my whole life against my basic nature? Fuck no! And why would he damn us to Hell if he LOOOVES us SOOO much. If He loved us that much, then he would fucking be here every day helping us out and letting us know we're protected, because he knows that it's hard to be here. Don't you THINK that if we KNEW he existed there would be less violence etc? They would know for certain they would get seriously reprimanded and therefore wouldn't do it. Anyway I could go on forever on how God made us a certain way yet the Bible wants us to work against ourselves, but that's basically my point. Why give some of us so many hardships and some of us the predisposition to be depressed and want to die, if in fact we act on our basic nature we will be damned to Hell? It just doesn't make sense. Especially because he loves us so damn much. You know who I think God loves? Himself.
So yes, it sucks big time because if I knew that I wouldn't be punished for killing myself, well hot damn, where's the shotgun?!
