I almost jumped off a cliff, but my SI ended up being too strong.
I had traveled well over 24 hours and even had to hike to get to the spot where I had chosen to do it. But once I got to the spot, I just couldn't jump. I think the largest factor in me not jumping was seeing the couple thousand foot drop below me, knowing I would've been in the air for a couple seconds before finally hitting the bottom. That that would have been my final moments. Something about it, I just couldn't bring myself to doing. I was even sitting down on the edge with one of my legs hanging off of it.
