I know exactly how you’re feeling, to get into my engineering college I had to do an interview, scared the fuck outta me. Breathing helped a lot, taking deep breaths as I walked into the interview calmed me down. I also told the interviewer that I had a stammer beforehand, that also definitely calmed me down. Feeling emotional during these things is completely normal. And just know it does get better, I left college and now I’m going to working for Mercedes AMG as a junior technician.
