If your T is a CBT (Cognitive Behavior Therapy), then she probably wants to get a problem and fix it and most don't care about the past and how it affects you. They tend to focus in the "here and now" and work on improving skills and changing thought patterns.

The type of therapy where you discuss your past affecting you in the present is some form of psychodynamic therapy ~ could be under the disguise of Object Relations, Schema Therapy, etc.

Ask her.
