Not feeling good about upcoming MMIs (for medicine)

Not feeling good about upcoming MMIs (for medicine) Hi all, I have a couple of medical school interviews coming up in a few weeks here. They use a multiple mini interview (MMI) model, where you have to answer tricky and ethical dilemmas in each station within a time frame. Unfortunately, I stutter, typically as a block in my speech. My dad was/is also a stutterer, so I know some genetic factors were definitely passed on to me. My stutter is not terrible in day-to-day life, but it always flares up when I get nervous, as for most of us. While I was doing MMI prep scenarios with a friend of mine, before I informed him that I had a stutter, he pointed out how my speech is often fragmented or disjointed. (The first time we prepped he called my communication skills "trash", but I think he's a bit more sensitive now haha...) My friend is much better at these scenarios than I am; to be honest it makes me quite jealous how fluently (and confidently!) he can speak. I've been doing prep for the interview daily and it seems like I can't improve. I guess you could say I've been doing some "exposure therapy" where I prep with random people on Discord. To give credit to myself, this is definitely more nerve-wracking than preparing with my friends as I typically do. I know, because even saying my name to these random individuals can be very difficult for me. My parents advise me that whenever I feel a strong stutter coming on, to let the interviewer know I stutter. It might even release the fear I have. It's a good idea; when I start "blocking" I can literally feel the inhibition within my body reverberating and closing my vocal cords. I haven't yet incorporated the skill of being so candid with the interviewer, but I should probably learn soon. I imagine more exposure therapy, too, is probably best to adjust me for the real deal. I've always been a very successful individual regarding academics, but I realize now how it was probably a redirection of my introverted energy towards a field I knew I could always excel in because of its solitary nature. I don't know. My older brother, who's married and is super successful as a lawyer, never got the stutter from my father. Sometimes I feel like I've been dealt a bad hand. I guess I just wanted to rant. If you have any opinion, thoughts or even similar experiences, I'd love to hear it.
