As far as I can tell that's all there is to our emotions in a moment by moment basis. Nothing metaphysical. No cosmic purpose or meaning. Just a function of being socially evolved creatures.
In the simplest of situations, yes, they work that way. But emotions aren't driven solely by single experiences. In any moment there many things collectively acting on our emotions. Not all are external either. Memories of past events and surrounding contexts also effect emotions. We can also experience multiple emotions at once. All of those possibilities get woven together into a complex pattern that is our current Emotional State.
Suffering as an emotion is not purely a result of pain. In some context at some times, pain can be an important part of good emotions. And even pleasure can be source of suffering. I have a current example of the later right now. My mother died 11 months ago. I inherited a bunch of money, and no longer need to worry about my retirement. On the face of it, that's a good thing I should be happy about. But it's also a reminder that she's gone. So mostly I'm sad about it. Two conflicting simultaneous emotions from a single stimulus, because of it's complicated context.
“Experience->Emotion->Action” isn't wrong. Just simple. Simple things layered and interacting with each other can become very complex very quickly.
You ask about their cause, then give examples of their effects? It doesn't seem you have a clear understanding of you're curiosity. Of course that is another emotion, so it may make sense.
Maybe I don't know what you're trying to understand.Emotions do happen. Not sure what alternative you're thinking of.
Calling them things is only a convenient short hand. They aren't tangible objects in any way. They're patterns of neuron firing.
Reading your OP again. Some emotions may have a functional purpose, to guide useful behaviour, others may simply side-effects of having emotions at all. I'm not sure suffering would be one of the former. Sometimes people choose to make good of their suffering. Building character or what not. But that's far from automatic. Often people gain nothing from suffering.
Yes. It's a problem to deal with for sure. But hating on someone who's disabled for their disability doesn't make sense. It's not his fault he can't understand what he's doing.
I'd be more curious what percentage are reporters that feel they need accounts
