I had 2 years of intense DBT group therapy after I moved. I was dealing with PTSD, anorexia, major depression & anxiety at the time I moved....it all improved after the move but learning new skills & reprogramming my neural pathways that jyst weren't working for me any longer. Looking back they weren't working well for me even during my computer engineering career & totally broke when I had a breakdown 13 years before I could get out of the marriage. Changing those neural pathways changes behavior though honestly I don't think they could have been changed if I had stayed living in that environment & I doubt I would even be alive now if I had stayed.....so the change has really been a miracle in my life.
