Yeah, I had to go back to work after I had a psychotic break there. It went better than I thought it would. Not too many people even acted like I'd been gone--and the ones that did comment about my feelings were my "work friends." My office was on the top of the building and it seemed like it was a dreadfully long elevator ride to the top--I spent it taking deep breaths. I hope it works out for you.
Oh, and I found out who my true friends were when I returned to work.
