I have nearly fallen off a tall building. Stranger nearby saved my life. I swore I would never forget them but I did.
I have swallowed poison that burned my insides and permanently scarred my tongue.
Everyone who was ever close to me is now dead or gone completely.
I was once shut in a box the size of a coffin and not allowed out for a few minutes.
I once woke up in the middle of the night when I was sick and had so much gunk in my mouth/throat that I literally couldnt breathe for a good 2-3 minutes.
I have woken up with all limbs completely asleep and unable to move anything but my head.
All of which were terrifying at the time, but what I am really frightened of is failure.
