Yes, therapy seems so bittersweet when you realize it's the best you'll ever have, but it's a "professional" relationship no matter what you want deep inside. I went through several therapists and some where re-traumatizing...mostly those who had the old training that dependency is bad.
Therapy has undergone a major revolution, where dependency and attachment are encouraged so that it can be worked with gently and allowed to mature in a natural way....like when a child who so loved his old blanket and finally decides he doesn't need to drag it around anymore, and his "good-enough" parent let that happen naturally without telling him he has to get over it, or else.
Just now, I can't imagine ever getting over my desperate need for my T, so I try not to put myself into the future. It just makes it all worse to second guess the future. And, besides, there is a lot of argument now that it's really anti-therapeutic to give a patient a deadline, or termination countdown. Who says you can't be in therapy with your T the rest of your life? I've known some who have gone to the same T for 30 yrs. It's good if you can grow out of your need for regular sessions, but maybe you won't, and who is to judge that?

I've been in deep therapy awhile and tend to have the usual terrors of how therapy will end and how my feelings for T could be mangled. But my T has turned out to be very good and trained in modern relationship therapy. I'm determined that I will do my best to reveal myself in the sessions, and try to trust in the development of my mind and feelings without too much worry about how it's going to play out. I just feel that worrying too much in advance only makes me feel bad all the more. But I know this is easier said than done when life has been so devastating in the past.
