Another thought in the A line?

I did this model earlier this afternoon and am wondering if another T can go in the A line or if I’m missing something here.

C: x said “thanks for today”
T: he probably wants to fire me
F: doubt (originally had shame here but I think it’s actually doubt)
A: ruminate about doubts (originally had “think he’s lying”, but I think that T is part of me ruminating in finding evidence that everything about me in this job is wrong)
R: I fire myself repeatedly in my mind

I am seeing that this is a pattern for me in so many Cs – the doubt and ruminating and finding evidence that I am all wrong. 🤯 How does my R look? What else might I be missing?
