I still have to find a remote location and find out when I can but thank you. I know what I'm doing now
I know it's your choice, this whole forum is to encourage people to make their own choices, and I don't know what sort of pain you're in right now. But I'm begging you, don't try this, unless you knock yourself out with elephant tranquilizer first, please, don't do it.
Most ctb methods allow time for regret to set in, but the agony doesn't last long until you're dead, but most of us have gone swimming and experienced that drowning sensation, or have maybe experimented with asphyxiation (not in the freaky way...maybe in the freaky way?), etc etc, but being burned is the one thing most humans truly have no complete concept of because we all have that knee-jerk reaction once we've been burnt and even then the degree of pain is not as severe as it would be if you stood there and let it the fire cook you to the bone.
Your brain will be wired to spend it's last moments screaming in agony and searching for water. And god forbid you're found and saved, you may survive or you might pass away in a hospital some days later, but either way you'll be in total agony the entire rest of your life. I can almost guarantee that once you've set yourself on fire, you would immediately rather live another 50 years with the pain you have now.
