What is the difference between nerve-wracking and nerve-wrecking? I can't find an entry of nerve-wrecking in the Longman dictionary. But I've seen sentences using nerve wreck. Wreck can be used as a verb. So I think it's natural to have such a word as nerve-wrecking, which can be used to describe a situation that gives people lots of pressure. Am I right? What do you think? Thank you for your time!
