The delusion feels real. I have a similar delusion, by the way.
My thoughts on why that delusion happens are pretty metaphysical though. But the understandable thing is that a healthy brain doesn’t generate that delusion anymore.
My approach to reducing and possibly stopping thought broadcasting entirely is first, a good antipsychotic regimen, then, loading up on antioxidants so that my weak blood brain barrier and compromised gut lining aren’t damaged by oxidative stress, which allows them, and the brain, to actually heal instead of deteriorate. I also have to avoid wheat and eggs and mammal meat to avoid certain pro-inflammatory compounds that may disrupt those barriers as well.
I’ve had luck in controlling my voices with that approach, since where they used to be audible and able to be spoken to, they now fluctuate between being completely off or barely noticable, after 2 months of trying that antioxidant approach (ionized water is my main source of antioxidants.)
I still have thought broadcasting though, to a limited extent. I feel that’s the final domino to fall, since having no TB means having a perfectly quiet, healthy mind that doesn’t look for synchronicities every second. But, I don’t interact with the radio and TV anymore, or at least today I didn’t.
