Finding unintentional thoughts

The model works great for me a lot of the time. (I’m not saying it’s easy to change my thinking patterns, just that it’s pretty clear what the unintentional thought is and what replacing intentional thought will be helpful.) When it works, I know it’s “right” because I feel understood when I try to practice the intentional thought.

But sometimes, I struggle to identify the unintentional thought. It’s usually when I’m feeling mixed emotions–sadness & shame; fear & regret; anxiety & loneliness. When this happens and I try to identify the thought, it feels like my logical brain is just producing a logical explanation. When I try to practice the replacing intentional thought, I feel the same frustration that I get when I’m trying to explain something complicated to my boss and he isn’t taking the time to listen. (My boss isn’t a native English speaker. Things get lost in translation.)

I’m sure it gets easier to identify the thinking with more practice, but at this point I’m really struggling and feel like I need a different approach to get around the wall of logic in my brain. Any thoughts or advice on how to approach this differently?
