Emotional Illusions

Maybe I am being pessimistic, however, this topic has been rolling around in my skull for some time.

Is what you feel always what is actually happening? When you feel that fluttering in your chest, does it mean what you think it means? You could be feeling you stomach growl for all you know, but you let something unrelated become your significant sign of emotional dependence.
When you feel upset about something, are you sure that the emotion you feel is not a suppressed emotion that was triggered by an unrelated event? How we as people, supposed to interpret things that we can barely begin to comprehend?
What is the reason for our constant misunderstandings? Our overwhelming need to attack the irrational with rational thought. When something cannot be put it a logical thought, why the heck do we feel the need to make it fit into a logical explanation? It merely distorts the original feelings that we were struggling to understand.
As people who say we are trying to understand and learn about everything around us, perhaps we should focus inward to figure ourselves out first.
