First time doing Model on paper

I just signed up and am working on my first model and having a hard time with C.

I’m in the middle of a career shift in which i need to study and pass license exams to continue. My T: is I’ll fail creating F: of discouragement and being disheartened. So I A: don’t study thereby ensuring R: I dont pass the exams. Which supports the thought that I failed but i cant seem to get the circumstance. Is it C: I don’t study? Or is it bigger, more than that? The same thing happens when i create an intentional thought of T: I’m good at learning cresting F:hopeful leading to A: scheduling study time R: studying and learning info supporting T: Im good at learning. My C is elusive to me!
