Is it JUST them calling that you're afraid of or talking on the phone in general?

I have a strange phobia and get anxiety when I think about calling people... I *hate* having to call people. I don't mind it if they call, I'm fine then. But when I have to call people, my hands get sweaty and I get VERY nervous and anxious. It's very bothersome.

Anyway, I hope somehow you can get your anxiety under control enough to just talk to your worker just once and tell him/her what is going on. You're in my thoughts.
