I find this self-dialog very interesting; in certain aspects it resembles the sort of self-dialog I teach people to use to throw off more mundane fears and mental/emotional blocks, outdated moral injunctions, etc.

There are a few places in what you're doing where a more focused approach would be helpful, though. For example, I would define an outcome and a test procedure: what are you attempting to change, and how will you know if you changed it? This alone will help you trim distractions a bit.

Also, generally speaking, the key to getting rid of an irrational belief is to clearly identify the past negative consequences associated with disbelief in that belief. Your expectations of what will happen in the future are usually either an irrelevant speculative extrapolation by your logical mind, or a simple projection from emotional memory... And it's the latter category that's relevant, as long as you focus on identifying the "near", sensory memory of the events your future prediction is based on.

In particular, you are looking for memories involving the loss of either personal status/significance, the loss of connective bonding, the loss of perceived safety, or the loss of available novelty/stimulation, (with these latter two being far less common), associated with either you or someone else failing to believe (or act upon) the belief in question.

The neurological phenomenon known as "reconsolidation" explains why access to the original memory is useful; it's simplest to remove an emotional attachment to a thought or belief by reinterpreting the original memory that triggers the emotions, rather than to build elaborate reroutings of thought "downstream" of the source.

Once you've identified the specific memory you're using to form your emotional/intuitive judgment (creating the fear), you can use further questioning to cast doubt on your original interpretation of events, consider other possible interpretations, wonder whether the situation is different, etc... and in the process, this sets up alternative lines of thought linked from the original memory, allowing you to have a different emotional probability distribution, so to speak.

I'm being necessarily terse here, as I know of at least two whole books that have been written on minor variations of this basic process: "Loving What Is" by Byron Katie, and "Recreating Your Life" by Morty Lefkoe, each proposing a different sequence and set of questions, but essentially following the same general process I've just described. I've also done workshops on my own set of variations, with slightly different scopes of applicability than either of their methods.

Either book, however, is quite good with respect to having lots of example dialogues to show how to apply their processes in practice, and either one would, I think be helpful in focusing your approach to this, or any other attempt to change an emotional belief or judgment.
