My T disagreed with my pdocs diagnosis. Pdoc diagnosed me with bipolar d/o. T dx'd me with Major Depression and PTSD. T understood why pdoc would suspect bipolar but disagreed. Eventually I brought it up to pdoc and she agreed with T. Unfortunately, with MH it is hard to dx and there is no exact science. Often some symptoms mimic traits of other of other dx.
My thoughts areif you like and are working well with T that is what is important
