Flippant model

Every model I write lately, I end up turning around the result (similar to how Byron Katie teaches to turn a thought around), and I think, as a result, I’m over-simplifying my models. Can you please help with the following example?

C: A coworker, who was recently promoted when I was not, asks for help and responds “Thanks all!” when I provided a 2 paragraph response with screenshots and examples and one other person responded with 2 words.
T: My coworker is so flippant
F: Resentful
A: Focus on coworkers’ flaws and other ways I feel she has betrayed me. Compare self to coworker. Complain about coworker to others. Avoid saying or thinking anything good about coworker. Avoid giving any credit to coworker in meetings. Avoid helping or investing time with coworker. Emotionally close off from coworker.
R: I am so flippant

As you can see, I basically just turned around the R from the T, which I do actually feel is true here, but since this often happens in my models (i.e., if the T is “Person or situation is X”, I decide that the R is usually “I am actually X”), I feel like I’m getting “lazy” in my models and taking some kind of model “short-cut” that makes it too easy :). (Yes, I realize that is just a thought too haha, but I want to hold myself accountable on doing rigorous models!! Thanks for your help!)
