The Mechanics of Emotions

I have this idea to explain all emotions than can be experienced by a simple mechanical idea.

Stability is when a system does not change by itself or through small outside disturbances. Instability is the opposite when a system tries to change itself unless an outside force forces it to stay the same. So for this argument... lets define stability as systems tendency to stay the same and instability as systems tendency to change itself. It seems like a logical inevitability for a system to be either stable or unstable or the combination of the two since parts of a complex system can try to keep the system the same and parts of it can try to change it at the same time.

While I can't see a practical way to test this, stability does seem for me to do pretty much exactly the same things in humans as emotions... We are clearly systems whose properties can partly be described through stability. Are our positive feelings the parts of our system trying to keep things the way they are going? Are the negative feelings the parts in our system that are trying to change the way things are going? And since there is an infinite number of ways to be stable, unstable or the combination of the two, all possible emotions could technically be explained by this. So could this be the mechanical explanation for the mystery of our feelings?
