Thought as a circumstance?

Dear coaches,
I’m wondering if I can put a thought as a circumstance if my model is about having “negative” thoughts. When it’s in the past (a few seconds after the thought appears in my mind), I suppose it can qualify as a circumstance. But my hesitation is because it doesn’t respect the rule that everybody would agree to this happening, since no one can read my mind (at least I hope so!).
For example:
C: Today I had the thought that this person looks fat
T: I shouldn’t judge people on their weight
F: ashamed
A: beat myself up
R: I judge myself
Thank you for your help.
