Calling the recount of lived/observed experience myopic seems [please see edit] like an attempt to alienate the GP from their experience. At the very least it is at risk of having that effect. While a therapist can help with handling the experience and navigation of this sort of phenomenon, how exactly are they going to alter its occurrence or effects? Will the therapist be refunding the lost salary? Will the therapist rewrite time to provide that promotion that was missed? Will the therapist inspire love or even camaraderie in the heart of the missed relatee?
In my experience these sorts of behaviors are pervasive, as noted they are subconscious, and their impacts are very real. The biggest problem is that you need to avoid expressing your needs and sidestep the headwind while additionally dealing with the emotional impacts while being expected to over deliver relative to peers.
[edit: I'm sorry. Some challenging topics here. Rather than visiting your intentions, I should ask: do you want these types of experiences not to be a part of hidden worlds around you?]
