I don’t know who to talk to

About this but I’m really nervous as I am excited LMAO I’m gonna be doing a peds rotation with a pediatric gastroenterologist who’s apparently very cool and my only impression of him was a pretty hearty like cowboy guy but ALL of my friends tell me he’s like super mean and super bad vibes and super hard on students during rounds and like meetings and stuff and I’m so nervous cause I lowkey feel like I don’t know enough and I like I also have to study for my exam of peds but like what he expects from me is different from what the exam expects so I have to study different stuff and I’m like AAAAH like idk like it’s so nerve wracking I’m afraid he’s gonna hate me cause I’m stupid :(((( and my stethoscope broke like a month ago and I haven’t bought another one im just scared he’s gonna expose me for the Larp I am
