We wont' give you advice or methods to kill yourself as this is a pro-life forum. We will, however, listen to you and support you any way we can, as we are good listeners and understand a lot due to all of us having our own problems.
Would you like to take to us about what's bothering you so much? You can PM any one of us, if you prefer.
I'm sorry you're in such misery right now. I can listen to you and support you but I can't help you kill yourself.
love and hugs,
least
