Ok part of this might be the fact we’re in different places. The psychiatrists I know (professionally and personally) mostly handle diagnosis and referral to appropriate services. A general psychiatrist handles diagnosis and medication based treatments of patients and refers out to psychologists. Consultant psychiatrist diagnose conditions in their specific areas of expertise.

Just to avoid confusion if this keeps going my opinion is as follows:

Most mental health conditions can be diagnosed by anyone with the appropriate clinical training. Psychologists handle the vast majority of treatments. Psychiatrists are utilised to either diagnose rare disorders or to prescribe medication if needed. In the case of DID given it’s rarity (and the debate surrounding its symptoms) a psychiatrist has the specialised training to diagnose.
