I used to think suicide was a legitimate option. I was fully convinced, even. but I really challenged myself to be honest about it, and after much deliberation here is what I have determined.
Suicide is the worst mistake any person can make. No matter how bad you feel, are you really going to make the absolute worst choice you possibly could? Don't. There is absolutely no reason suicide should occur. I guarantee you, if you were somehow able to communicate with yourself after committing suicide, you'd be talking to someone entirely consumed in regret. If you're thinking about suicide, I want you to have an imaginary conversation with yourself after having done that, and I want you to truly try to empathize with what they are now. They have nothing, and will always have nothing, they are nothing. Your situation is bad, but at least you have life. At least you have yourself, no matter how bad you are. They have nothing.
Do you know what nothing really is? Before you send yourself there, I want you to be honest with yourself like I have and imagine what being nothing is. Coming from someone who has a strong tendency to leap before they look, this is one situation you must do so, because there is no coming back from that decision.
When I put myself in that situation, I always think "damn. I know he thinks it's bad, but it's better than what I have. I have nothing. I am nothing. I would do anything to wake up another day and just know I'm alive. I would trade anything for that, but I have nothing to trade."
Think about it, if you must, but never, ever do it. To never experience, to never think, to never feel, to never be ever again... and you can never change it, you will cease to exist for eternity. Your sheer ability to even consider making such a decision is a result of you being given an amazing gift: you are alive. You came into existence. Why would you give that up? Every other possible mistake someone could make is better than ceasing to exist, from an entirely selfish standpoint.
