How do I get around the fear that I am annoying someone by my stutter or that I'm inconveniencing someone.

How do I get around the fear that I am annoying someone by my stutter or that I'm inconveniencing someone. So I'm scared of starting as a medical student on the wards. I'm scared that for e.g the resident will ask me the drugs the patient is taking and I'll stutter and just annoy him. Ugh I want to rid myself of this fear before I start out.
