I've had a very bad period in my life, my best friend turned against me and all my class was laughing at me, teasing me, beating me, spitting at me etc. It went on for 2,5 year.
I thought much about suicide, and wished I had a button that would simply make me disappear. I kept imagining it is in my hand and I was pushing it.
I drank some stuff I thought might poison me, twice, but it all ended in a great belly-pain and stomach problems, nothing really serious. I thought I should try something else. I thought about jumping off the window or blowing myself up.
I opened gas and stood next to the window with matches in my hand. Then I heard the doorbell, so I quickly closed the gas and ran to the door. And so I didn't do it. I probably wanted to do it this way because I thought it might look like an accident.
Eventually, decided that by killing myself, I would do much harm to my family, which - being shitty as it is - loves me in some way.
