How long have you been working and how bad is the stutter? I've always had a moderate stutter but it got worse when I talked to people I didn't know. I moved and started working at a retail store and I had to talk to costumers, make calls and answer phones. The first months were hell and full of anxiety, but the coworkers were really cool about all, and little by little I began to improve. Now two years later I still have a stutter but it's nothing compare to how it was.
