It is very interesting what you are saying about all of your emotional energy going into therapy and withdrawing much of your emotional energy from others in your life. I can recognize that very clearly from my therapy, and that has been going on for many years. I never really thought of it as being wrong. But now that you put words on it I can see there may be a problem. I always thought that it was important to put your emotional energy in therapy to make it work. And I don't see how the therapist can prevent that. My therapist was very available, and very professional. He sincerely did his best, and he was good in what he was doing. But something went wrong somewhere. He did sometimes or maybe even often say to me: "Your life is not here in this room. Your life is out there". So he actually tried to make me change this. But for some reason I couldn't.
You say that it took a long time to dig out. How long? Did you manage to do that on your own, I mean without seeing another therapist?
