I've learned that feelings can be based on thinking that is sometimes not terribly rational, helpful, or accurate, and so often that thinking is based on old beliefs I took on years and years ago that are quite mistaken. T always has me work from what were the thoughts that flashed through my mind, usually in a matter a seconds. Then I need to really evaluate those thoughts for reality and accuracy and rationality. Once I can see where my thinking is inaccurate, I find the intense feelings that were based on errors in thinking really do neutralize and become more proportionate to reality as opposed to being disproportionate based on mistaken beliefs.

So maybe it isn't so much the feelings that are the problem. They are just a response to the thinking. It is the thoughts that can definitely lie and steer our emotions astray.
