answer:I actually don’t know many people who only have one. Perhaps me and my friends are insane, but a lot of people I know will be diagnosed with one disorder and suspect they have another, or suspect they have multiple disorders and are diagnosed for none. I think if you get diagnosed for one disorder, you are probably seeing a psychiatrist who can possibly notice that you have other disorders over the course of your treatment. Kind of like going in for the first time is half the battle.
