I joke on here a lot that I have high blood pressure problem due to anger and all that stuff. In reality, my friends typically would describe me as being calm all the time and kinda cold. Actually, I just asked some of them last week and that's exactly what they said to me.
My experience is that emotional people seem to be proud of the fact that at times they allow their emotions to get a hold of them. After all, it feels good to act out in anger. It doesn't stop at anger. Rash decisions and actions during strong emotional state typically brings about a satisfying feeling. That's why it can be addicting to people.
FEY, a word of advice, and I know you hate me right now. If you ever hope to better yourself and bring yourself closer to truth, following your strong emotions sure as hell ain't the way to do it.
When I was a cop, an old cop gave me a very good advice. If it feels good to do it, it's probably a bad idea.
