Does dr/pt confidentiality still count if pt is an rn and both work for same hospital

Hi, i was wondering if i were to disclose to my doctor about my recent experimentaion with an illicit drug, would he have to report me to the hospital since we both work for the same institution. I would never even think of going to work if i were not 100%, and i would never risk my pts' safety, just as an fyi. I have not been feeling right since i did this and wanted to go to my doctor, but am afraid that if i do i may be putting my job at risk. As a pt should i not have the same confidentiality rights as other pts, despite my job title?
