We were setting up a long-awaited, much anticipated new stereo the other day. When we initially turned it on, the sound was terrible. I immediately got that sinking feeling and started to think that the stereo might turn out to be a lemon (it wasn't).
Afterwards, I was looking for a word to describe that creeping feeling of dread that a much desired thing or event might turn out to be less wonderful than anticipated. The best I could come up with was "anticipatory disappointment" and that's not even a single word. The word I'm looking for describes that combination of fear and hope that might have one both praying and swearing at the time. Any thoughts?
