pain of a thousand swords
When pain is so intense, it's like having a thousand swords going through you and laughing at your misery.
I failed my driving test for the third time. My brain felt like it was being stabbed by a thousand swords.
My dog peed on my brand new couch. I screamed so loud, I think the swords heard me.
I got bit by a million ants and it felt like a thousand swords were poking me.
