If your therapist does not understand your situation WAY BETTER than you do, they won’t do you much good. And because the understanding of a good therapist will very META (above and more comprehensive) to the details you are tracking, you might actually think they have the wrong focus, or don’t understand your situation. And that would be quite wrong!!
Sadly, lay-clients are incredibly bad at assessing therapist skill & quality, and also prone to assume you have your hands on the wheel of the problem.
In fact, there is a “homeostasis preservation” program running in your firmware (unconscious programming) that drives you to pick a therapist who’s not very good … someone who won’t destabilize you (identity or worldview) in any substantive way.
So, the answer to your question is to trust other people with more experience.
Pick a therapist based on THEIR reputation, not on YOUR JUDGEMENT.
