The only time I disclosed my psych diagnosis (and only one of them) was when I was still on medication for it. And the only reason I felt it necessary was because the mood stabilizer I was on for mood disorder NOS is, also, commonly used to treat epilepsy. So, I felt it important to let them know that I did not have epilepsy, as given the reason I was in the hospital that tidbit may have been important. Other than that, I have never felt it necessary to disclose my diagnoses. I would imagine I might need to disclose my eating disorder one day, but I can't think of an instance where AvPD would come up.
