I know exactly what you mean.
I had to do this with my mother for most of my life as well. She's a bi-polar taurus with serious rage issues. For most of my life, I simply didn't allow myself to get upset in situations where I had an absolute right to because it simply wasn't worth it. I truly didn't understand how most people simply let their emotions control them.
I ended up getting hooked on amphetamines for a few years, at which point I suddenly wasn't able to control my emotions in the way that I had always been able to. I've since quit and, currently, I'm at a bit of a middle ground where emotions affect me more than they used to, but not nearly as much as when I was getting high.
That period of my life actually helped me to understand NT's and how it is that they can let emotions rule their lives in the way that they do. Before the amphetamines, I never understood how or why people let themselves get so mad, or make irrational emotional decisions. Now, I understand that they simply have no choice in the matter. In a situation where you or I would be able to detach ourselves, it seems that, for the most part, NT's essentially have no choice in the matter.
