Isn't your therapist psychoanalytic? I've found that style of working brings out intense transference and feelings of dependency on the therapist.

Both of my long term Ts are psychoanalytic, so the needs represented my child needs rather than adult needs. It's not that they are separate, its more that the child parts are drawn out front and center. The transference gets really intense, sort of covering up the adult. In session, the adult may dissapear completely leaving me feeling literally like a child. I have dissiciative issues too, but not referring to that here.

I don't think the containment needs to this degree as adult needs as much as I think they are feelings from the past surfacing in the present.
