What is a good, healthy, unhurtful, socially positive way to express anger? - lemm.ee

Once a therapist told me that a lot of the time anger is a secondary emotion; that is, it’s an emotion that comes out of another emotion.

So you don’t necessarily get angry out of nothing, but you get angry because you’re scared, or disappointed, or you feel wronged, or something else.

So their recommendation was to identify the emotion that’s making you angry, and express/rationalize that instead.

I get angry because of frustration about things beyond my control that impact me negatively and can't simply be ignored. Knowing that extra step is great and all, but doesn't reduce the frustration or the anger. I'm sure that identifying the difference is helpful to some people who can ignore or address the actual cause of their anger.

Note: I don't get angry about frustrating things that I can do something about, or can be ignored.

Why would you let things you can’t control have any control over your emotional state?

Seems more productive to get angry about the things you can change.
