Yeah, very good point. Rational thinking while being in a hyper emotional state is extremely tough. I think the trick is not to rationalize every thought and emotions but rather to reach an overall state of "acceptance" that emotions can be "irrational". This is more of a practice in meditation or in stoicism that slowly gives us an ability to make rational choices while acknowledging that what we are feeling right now transcends logic and reason and the futility of having a discussion with it or indulging in it in an investigative sort of way. For example: a stoic asks himself if the anger that he is feeling adds any value to the situation at hand. He reminds himself that this rush of emotions impairs his ability to makes rational choices and it is stupid to let it control you so much. Just this reminder to yourself every time you feel anger weakens it over time.
