For me there was a point when addiction had taken over, and it included:
-Feeling miserably dependent and living session to session
-Getting little from my sessions but being unable to quit
-Aimlessly digging into my past to stir up painful memories without purpose
-Not having any goals or way to measure progress
-Self-absorption with a focus on analyzing every minutia of my life
-Preoccupation with my therapist and our relationship
-Constantly comparing myself to my therapist and never feeling like I measured up
-Jealously towards other clients and a strong desire to be a part of my therapists personal life
-Obsessive emailing
-Loss of reality (ie strongly feeling like my thearapist was my actual mother and loss of understanding of the professional relationship)
-Ongoing arguements with my therapist
-Traumatic responses after ongoing arguements with my therapist
-Regression and destabilization
-Having a vested interest in staying sick as not to lose my therapist
