See if treating it like a trigger and looking for what is "really" wrong helps? I get road rage, which I don't normally, and I have trained myself when I recognize such an extreme anger to look at where I am feeling helpless in my life.

I can't stand to feel helpless and use anger to "re-energize" myself and get myself out of it. It's kind of like when you paint yourself into a corner? It requires something equally extreme to get you out?

See how you use the extreme emotions, underneath you are probably anxious/scared, frustrated or feeling helpless or worthless? If you get curious and go looking for what is underneath, the "red flag" emotions will instantly go away because they did their job.

It's like dreams of monsters chasing you and how they tell you to turn around and confront the monster to get rid of it.
