What are you even so afraid of? probably the same as most of us; stuttering. or having people hear we stutter. worried about what they'll think, especially during med school interviews, yikes! I know a few people with stutters who also went through med school interviews and wish I could ask them. I think a lot of them advertised somewhere during the interview (usually at the start) that they stutter to put it out there and give themselves more permission to stutter if it comes up. Im really wary on giving you advice since im not a med student myself but I hope you know that stuttering somewhat isn't a dealbreaker and you could probably even turn it into a strength, like it could give you a better understanding of how people facing adversity feel and has made you a better listener. That's up to you. I just want to wish you the best of good luck!
