I have had a couple therapists - each with their own specialty - tell me they had reached and shared all the conclusions they could regarding my case. I believe they were being honest with me; no additional therapeutic digging was going to unearth a miracle insight that would suddenly free me from my depression.

One of these therapists suggested that for the long term I continue with the meds and handle depression as a kind of chronic pain scenario. That's not exactly a happy view of things. I hope you can eventually find a more encouraging framework for what you are experiencing, Pierro.
