Can a thought be a circumstance (and vice versa)?


I’m practicing models for the first time (for the first time for real, anyway).  I’ve tried doing them in my head during Brooke’s podcasts.  In the case of an addiction related model, I’m getting confused about the difference between a thought and a circumstance. Here’s what my models are looking like:
MODEL #1
C: I keep compulsively checking LinkedIn, email, etc.
T: I’m exhausted/stuck and need a distraction
F: Frustration when nothing good comes of it…and elation when something good does come of it (like an email from a new prospect).
A: Keep checking!
R: Not enough time to take the actions I know will lead to results, like working on current client projects or developing plans for getting new ones.

MODEL #2
C: I keep compulsively checking LinkedIn, email, etc.
T: Ugh, WHY do I keep doing this!
F: Icky disgust with myself.
A: Keep checking, because maybe THIS time there will be something important/exciting.
R: Same as above.

So in these cases, it seems like it’s very circular: The thoughts keep causing the circumstance to happen over and over.  This seems to happen only with this addiction type circumstance. I tested the model with a circumstance about someone else “My husband did X,” and one about myself that wasn’t addiction-related “I didn’t finish an article I planned to finish today,” and none of them give me this loop.

Am I doing the original model correctly?

Thanks!
