Whether it's the "right" track or not, you're on a very similar track to how I look at it. My experience has been that whereas "negative" emotions are definitely real and authentic, they are often based on missing information and misinterpretation of something.

We reactively get angry at someone or something, but if we just take a moment to "sit with" that anger and observe the underlying "why," we often discover something about ourselves... and the person/thing who would have been the recipient of our anger is largely innocent. One of my spiritual teachers of long ago used to call it "reacting to a memory," (rather than the present moment).

I prefer not to give expression to a lot of negative stuff simply because... what does it resolve?
