Kate:
That is always the question, move or stay. Give up the known comforts and friendships that have been built over the years, or go to a new place for the opportunity of new experiences and new friends.
You have pretty much described what you would miss if you stayed. But I would ask what, really, is giving you the urge to leave? Everyone knows you and your story. And you know that they will always, always, remember that. It may not be the thing they think of first when they meet you now, but it will always be there. If you move to a new location, chances are the folks there will probably not know of your past initially, but they will find out sooner or later. You can never erase the past, and as you said, you would not try to hide. So sooner or later, you will again be "other".
Initially, I moved away. Not incredibly far, because I did not change jobs, but far enough. Living in a metro location like Chicago, you don't have to move very far to have neighbors that have never met you. I moved in with my friend, Julie, and together we worked through our transitions. Basically having the pact of being 24x7-40 (out everywhere but work).
What I found as I worked to become who I am, I missed my family more and more. I could visit anytime, but it was about a 45 minute drive and so it was only on weekends that I would visit them, or they would come to see me.
As I went full time, I had contemplated staying where I was, or moving to a new location but away from where I grew up and where my family was. But in the end, facing the real possibility that I would be alone, I found the draw to return too great. I returned to where my family was and bought a new house there. And I have been the happiest I have ever been in my life.
I know your experience is different, of course, Kate. But the question that you need to answer for yourself is still; is the urge to leave greater than the urge to stay?
