It's okay to freak out as it's coming up for the new year so we're all freaking out and partying


And to reduce the chance of being brain damaged just make sure you're not interrupted and don't partially suffocate yourself with the rope or do anything else that'll risk interrupting the process before its finished. So make sure the anchor point and both of your knots are secure by testing them out properly before you 'think' you're gonna do it for real.
Only go thicker with cotton for full suspension, partial is fine.
Put the rope just below your jawline and just above your Adamsapple and don't drop into the noose, lower yourself slowly otherwise in partial you could risk the noose slipping up or down slightly.
Pad your carotid artery area with folded socks of the rope doesn't work on its own.
