What about Distrust? When a situation makes you rethink previous experience due to present moment knowledge newly acquired?
I would think of this as trusting more intense/recent evidence over what has occurred before that. The process of inverting a belief does seem extreme enough to warrant generating distrust as a general warning, informing the intelligence: ‘’Warning, this situation is unpredictable, or not understood well enough.’’
A strong emotion like that can make a person steer clear, as well as focus on the source of it. If it’s understandable, then the concentrated attention will eventually elucidate understanding; at which point the distrust should fade, I should think, to allow the person to act on their newly developed understanding.
With that throw in Suspicion. Doubt. Regret. Possibly even Remorse. Move on to Foolishness then Anguish, since that covers "excruciating or acute distress, suffering, or pain" in its definition..
None of that rises to Fear and might or might not involve Love. It can be a very powerful feeling and life changing experience that changes your whole outlook on and view of the world as you know and/or knew it.
There's a little more than a binary sequence to it.
I think ivan's idea is, that much like a color spectrum, you need three basic points (1, 0, -1, love, neutrality, fear) to create a plane with all possible variety. If you put the shortest visible wavelength on the left, the longest visible wavelength on the right, and zero intensity at the top; I believe that covers all the possibilities.
If you love this and that, and fear these and those in determined amounts, that particular system may carry a name of a mood constant, and we may behave towards sustaining or changing the current mood.
Such a melting pot of moods might be considered an ambiance. Certain combinations of surroundings may be especially beneficial/agreeable - like a number of ingredients in various amounts will create a recipe with varying degrees of success. Even though your tongue can only detect a few tastes, the magic, and therefore the valuable data, lies in the proportions and intensities.
