Am I feeling Ambivalent or is the Ambivalence elsewhere?

We are never be sure of our feelings entirely.

We know the names of basic emotion such as joy, sadness and anger. After we learned that these first feelings are easily distinguished, we discover the are more complicated ones that are blended combinations of two or more feelings. And yet, there are more that cannot be named, described or foreseen in a single word (or perhaps within one sentence or longer). When something happen, there can be responses that be varied but never the same. There is one word however that shares many feelings that differs each other and can occur in one time and place. It is also possible for opposing feelings can be in one person as well.
