Alright. Hopefully your memory comes back eventually. The idea of anger not being a primary emotion is an interesting thought I hadn’t considered before.

I’m afraid the article you linked also says anger can be a primary emotion or a secondary emotion.

Is anger always a secondary emotion?
It makes sense to feel angry as a response to injustices, perceived threats, or frustrations, and anger might truly be your primary emotion in the moment. It isn’t always masking another, more vulnerable emotion. For example, if an acquaintance made an inappropriate, derogatory comment about you in front of others, you might immediately be angry that someone unjustly crossed a boundary. In this case, anger is still functioning to alert you to something getting in the way of your goal (e.g., of respect), plus it’s an immediate, instinctual response to the situation.

Tbh I’m not a big fan of the article. It does not match up very well with my understanding of the emotions.
For example, Anger is a problem-solving emotion. Fear is the defensive emotion. Yet the article seems to mix up the two.
