It's never come up with my T... I think for me personally, I would need to see any T for at least two years. I have been seeing current T for a little over a year and I JUST started being able to fully open up. And of course progress and healing can't be made if I am not putting everything on the table. (Naturally I'm moving away next month, just when I've gotten comfortable with my T...)
That said, my goal is not to need therapy long-term. I have a few issues -- substance abuse, eating disorder -- that I do not have a hold on and I need support while I'm working through those. I also was recently diagnosed bipolar 2 and I'd like to be around a therapist long enough that she can see me in different episodes so we can learn together how to work through them. But once I feel secure in recovery, once I feel I understand my disorder better... I would prefer to be on my own and rely on myself to use coping mechanisms T had taught me. I don't want to become dependent on therapy.
