I don't have any advice to offer you, except to talk to your T about it. I can give you my experience...

I used to have mother-figures in my life (I guess you could call it positive maternal transference with some definite counter-transference). I found that the pattern was older women in a caring role (teacher, doctor, counselor, T, Pdocs). When I found ex-T I discovered that she was actually younger than me by a year. I thought I wouldn't attach to her, but I did. It wasn't transference. It was attachment. Then she abandoned me. I swore to myself that I would never attach to anyone again, especially a T. So I met current T one month later. We both agreed that we didn't want me to be overly attached. And problems in the beginning of our relationship helped with that. But as time went on, and our relationship developed, I developed a deep attachment for her. And now that she's going on a 6 months leave, she wants me to attach to someone else?!?! I, of course, don't want that. I don't even like how attached I am to T. But I guess I haven't learned enough about relationships yet, or how to care for myself. Or maybe that's just who I am? T says attachments are healthy and normal. It's the dependency is not normal. I guess that makes sense.
