OOO good question. Some people often have fantasies about moving "away from everything" but then come to their senses and realize they would still be there with their struggles. Even after asking yourself,and your T, many questions, the decision is still a tough one, imo.

How long did it take you to find your T? How long did it take to build a trusting relationship? Are you basically finished with the heavy therapy so you won't have to discuss "your entire life" with a new T? Are you at a place in your life that you feel you can make a move without falling apart or needing T to "hold your hand" while you get settled in? What are the payoffs of moving? What are the minuses to losing or changing therapists/therapy styles?

There have been many patients who "follow" their doctor when the doctor moves, even out of State, they consider that relationship so important to their health. Continuity of care is very important.
