I found that normally they had not reason to talk to each other about me. Pdoc was in charge of meds; T was in charge of therapy. Their responsibilities didn't really cross often. They exceptions were if a) my mental state was so unstable that I needed hospitalization, or b) something with my meds was needing adjusting because it was presenting as an issue that was showing up in therapy - like increased anxiety, depression, sleep issues - particularly if a med had been added/changed in some way. Otherwise, they didn't really need to talk. Pdoc didn't try to therapize me; T didn't try to medicalize me.
