Thinking of talking to a therapist, I'm curious to hear what others have on this interpretation (which I openly acknowledge as "could be wrong" and I've never seen a therapist aside from once in couples counseling where they asked if I was ever diagnosed with aspergers): you grow the feelings you feed. What I mean is: when you dwell on things and focus on them in therapy, are you feeding negative emotions or traits and growing them? Could seeing a therapist make it worse?
