Okay - Maybe I am going about this the wrong way round.
Emotional success doesn't have to mean "I-am-so-happy-and-bubbly-and-soooo-happy" type of personality. Indeed, I find this people deeply suspicious and unlikely to be really happy.
But, according to some serious research, the kind of experiences that make people happy aren't relaxed moments or moments of self-indulgence and contentment...
They tend to involve the following elements:
- challenging activity that requires skills
- merging of action and awareness
- clear goals and feedback
- concentration on the task at hand
- a sense of control
- loss of self-consciousness
- transformation of time.

Therefore, I am pretty sure that being dissatisfied with something doesn't stop from being happy - once you set actions in motion to address the issue and you feel in control.
I suspect that Jesus kicking the merchants out of the Temple must have felt very happy - He had been enraged by the desacration and was doing something about it and being successful... Good stuff. Similarly when he was preaching and multiplying bread and fishes... A kick-ass sermon, plenty of people listening as if he was the Messiah - He must have been in the zone...
Of course, all those criteria could also be fullfilled by a serial killer as he is stalking and then killing his victim.
But I do think that this is directly opposed to being depressed. And it is important stuff as, after all, society was invented to enable people to pursue happiness - life, liberty and inalienable rights being the means to that end (with thanks to Benjamin Franklin and Thomas Jefferson for that one).
