I'm so sorry you're feeling so down. I was in that same place many times so I know what it feels like. In December was the most recent and it took everything I had to go to work in the morning. I just wanted to shut my door and not come out til it was quitting time and then I'd go home and be a lump there. April is pretty soon, so it's not much longer to see the doctor. Until then, come here, open your windows at home, be in the sun, really I think that helps a little.
I also had to add that you really are brave to be a nurse with this phobia. Alot of emets would have scrapped their dreams and gone to something safe. You should be proud that you went ahead with it!
In memory of the sweetest german shepherd I ever had the pleasure of knowing. I love you, Duncan. 3/12/02 - 12/19/11
