Overwhelming urge to snap this key off in the lock

Ever stood at the edge of a ledge & had to fight the urge to jump, or see a button that should never be pushed but have to struggle like crazy not to push it?

Well every time I do this I get an overwhelming urge to snap this key off in the lock - I'm not sure how many more times I am do this & keep managing to fight the urge.
