feeling sick...very sick

have you ever been called by your boss's boss's boss? and been called by name, and asked why you didn't do something that you were supposed to do? yeah that is about the most uncomfortable i have ever been. ever. it left me shaking in my office. lets say that i am only now beginning to fight down the panic. in this economy i do not need to screw anything up... i mean i work for an Investment Bank, this is a very bad time to hope that your mistakes aren't as bad as someone else's! i think i am going to be sick again....
