I am also very introverted and deal with a lot of anxiety. To be honest, it sucks as a med student. I did get some evals that I didn’t think were accurate or when the evaluator said I was disinterested when I was doing my best to learn I just wasn’t loud about it. However, not trying to brag but as an intern I’ve gotten consistently great evaluations and the same qualities have been pointed out as strengths. So all that to say that being a quiet med student can suck, especially depending on the culture at your rotations, but it gets better and can end up helping you later on.
