I am drawn to this post, and the kind of thinking that takes a step back. I am inexplicably addicted to therapy too, and it eclipses my real life relationships in impact and preoccupying force. Besides Oxytocin in relationships, I wonder about dopamine in addiction. One particular part of the brain habituates its dopamine release to a stimulus, and correspondingly reduces dopamine in response to normal/ common things. For some reason, my T is more influential on my brain than anyone else, and I do feel some kind of neurobiology must be involved. I am very interested in your thoughts and quest.
