This article is not accurate. When you are suicidal it is very hard to explain. You are miserable and in a lot of pain, you have negative racing thoughts about how terrible you are and what a horrible person you are etc and that the world would be better off without you, and you never really fit in, people just took advantage of you and abused and bullied you so you don't feel like you are connected to this world anymore, that the only way to end your suffering is to kill yourself. Logic, reason, and anything else no longer works for you, you can't think straight anymore and any thought just hurts you like a hot knife slicing into your brain. Every bad moment in your life plays out in your head, and each one just kills you inside a bit. You cannot even remember the good moments, you cannot recall that you have friends and family members who love you. You feel like nobody cares about you and everyone hates you and wants you to die.
I really don't know how I got out of it, except my attempts failed because I didn't do massive things like gunshot to the head or whatever, I did things that could be undone like overdose, etc. It was the only control I had at the time to survive, pick my way to die, and pick one that others can undo when they find me.
I got so sick working, that I developed schizoaffective disorder from the stress, and workplace bullies who abused me daily. I was a top-notch programmer, but now I am on disability trying to get my act together. Not being surrounded by sociopaths is helping me to heal up.
