I know exactly how you feel. I 25 M am in grad school. The required speech class I had to take freshman year was awful. I know exactly what you mean when you say you feel out of breath and mentally drained. I really don’t want to come off as preachy. I know what I’m about to say is a big ask and might seem unrealistic at the moment, but be kind to yourself. If people judge you because you stutter, screw them they aren’t people you’d want to be friends with anyway. College is a fun and scary, but it might be the single time you’ll be surrounded by this many people in the same stage of life as you. If your college offers it you could always try joining a club, or trying to get a study buddy in a class you’re in. Once you start interacting with a few people the doors will open and you’ll have a bunch of people you’re interacting with. I’ll get off my soap box now. Stuttering can be super frustrating, but just be kind to yourself. I know I speak for everyone when I say we’re here for you. My DMs are also always open if you someone to talk to.
