You are right, I should do that and should have done that. In Mexico things are a lot different from US or UK. Most of the agreements are done verbally and most of the pdocs and Ts don't make you fill any paperwork (specially Ts). But with previous Ts I had been, there was always a verbally agreement that all information I gave to them was confidential and would be told to third parties ONLY if I was a threat to myself or others. I guess this last time I was so zombified by the meds I was taking (thanks to that pdoc) that I didn't even had that verbal agreement. But at the end I learned something and I will be more cautious next time I see a T (if I ever see one!).
