I get terrified when the phone rings(actually its a beep in an earpiece). all of a sudden I can't speak, my tongue gets stiff, and my heart feels as if its going to jump out of my chest. At times i can control it most times I can't. It's embarrassing because when I can speak it starts as stammer and stutter and it makes me dread having to answer the phone because im afraid of embarring myself especially around co-workers who can answer the phone without any issues. I've looked this up and can't find too much about it so it's hard to get people to relate to it. Has anyone heard of this?
