Is it a "fight" response or an anger response? For me, my fight response isn't and never was emotional. It's a very disconnected state, where I'm aware of what's going on and what I need to do, but I'm not invested in it or the outcome. Like I know what I need to do to take out the other guy, but I'm not worried whether I'll be able to or not, just that I am going to do it. For a long time, I thought I enjoyed fighting and getting into dangerous situations, but I learned that I was trying to get that empty state that was a consequence of those situations. I really didn't care what happened to myself or anyone else as a result of those situations, just that I was there and I was able to cleave myself away internally.
