Jennifer, don't worry about going back to your last therapist if she was helpful to you. Of course you're "dependent" on her, you're a "team," you're both working on your health. You're dependent on your medical doctor too to help you when you have something physically wrong to help you figure out what it is and what to do about it.

I went back to my old therapist (wouldn't go to any other) after 9 years. It was the best thing I've ever done for myself.
