I'm so sorry!!! This sounds like an extreme violation of your rights and could be a legal matter if the address was in use and someone received this information. I so, so sorry.

As a side note, this is a prime reason I don't feel I should be in charge of anything serious. I make mistakes in the regular, regardless of how closely I pay attention. I could see myself making this kind of mistake. I did something similar and scary before. It should have been easily caught by our shipping department but it wasn't and it created a big to-do around the office. I feel bad for you most of all, but I also feel bad for your doctor. They probably don't mean to be so pathetic.
