I got an email back from my supervisor, saying he was just checking in because last week was quite difficult with the patients. He apologized, and said he didn't mean to pry. Then he said he has suffered with anxiety and depression, so he will hold what I told him in confidence. I feel a lot better now, and I think telling him was the right thing. It's amazing how crazy I can make myself with obsessing about things! I do have a secondary Dx of GAD, so there you have it.

thanks again everyone, you really helped!
