Oh, certainly. I worked with a LOT of mental health professionals - in my actual job, I mean - and one of the things I learned from them is that it can be very, very difficult to heal, psychologically, unless the person is encouraged to grieve over the changes in their identity that will result. Our experiences do shape us and that's just as true of the bad ones, so the fundamental change that comes with mental and emotional healing can be very, very disorienting. People will run from it unless they have solid support to work through.
