Study the illnesses and diseases that are less talked about, stigmatized, or uncommon. I don't want to hear any more excuses about psychiatrists not knowing about DID, BPD, Psychosis, etc. Learn about it, educate yourselves, people are relying on you to diagnose us properly, destigmatize it, and help us get treatment for distressing symptoms. You shouldn't be unwilling to learn about or unwilling to work with people with certain mental illnesses. They're coming to you requesting help from themselves and their symptoms, don't remain ignorant on purpose.
