Sorry for the long post guys! Talking about my stutter

Sorry for the long post guys! Talking about my stutter I'm 23 , currently a 4th year medical student. I am a stutterer since I could remember. But I didn't believe few years back that I actually stuttered. My stuttering was not repeating syllable rather worse, speech block. Tbh it never bothered me coz I was so good at evading/substituting or just changing the phrase when I was about to block. Never stuttered while talking aloud in class ,I even did drama in school. My blocks usually came when visiting shops and asking for a specific item. I could have 2 hour conversation with the shopkeeper but couldn't utter the item I was supposed to get. I always avoided thinking about my stutter coz I believed it would make it worse. Before coming to college I was anxious but also excited, I was always playful and outgoing so moving to a new place triggered excitement more than anxiety. My first year of college went like a breeze , I did dramas and skits , seniors also praised me for the wonderful answers on stage after the skit was over. I breezed past my vivas in the first university exams. Back in my mind I always believed that I did so well back then was because I didn't think of stuttering at that moment. I always feared what would happen if I did think of words in those situations where I was fluent would I be able to utter those words? Guess what,these thoughts got my stuttering worse, I used to try voluntarily thinking and forcing out words just to prove myself that I could say those words. Then my 2nd University exam vivas came , I had the worst stuttering experience of my life in that exam. I couldn't utter the answer I knew , after 10-15 seconds which felt like minutes I got the answer out. The professor told me to relax and breathe ,which actually for the first time in my life made me feel terrible about my stutter. I know she didn't mean to hurt me but it made me really depressed and frustrated. It's been 6 months since that incident but it still instigates fear. Sometimes I wonder how would I handle clinical cases with consultants if I block. Evading and changing phrase in not really an option in medicine. These thoughts do keep me up at night sometimes. ​ Does it get better with time?
