Job interview was brutal🙂‍↕️

Job interview was brutal🙂‍↕️ Just got done with an interview for a tech internship, and I’ve never felt so worthless in my life lmao. I spent days preparing on what to say, as well practicing with the mirror for hours. The first half went well with a few bumps, but my god, the second half just went downhill. I practically stuttered and stopped like 80% of the time. Whole time I could tell from the eyes of the interviewers that they probably thought I was stupid as they were always looking away when I stuttered. I wish I was able to actually speak my mind and not be born with this disease, I’m scared I won’t be able to get a good career post grad cause of this stupid problem
