It's my first interview ever, for a part-time fast food job, and I'm so worried. I'm very bad at talking about myself, don't have anyone to practice interviews with, and am just incredibly socially anxious and it's painfully obvious.

I don't know how to get through it, and if I do somehow get the job, I'm not sure how I'll be able to deal with working there. I have sensory issues and sometimes I really can't deal with being in public for everyone to scrutinize. But I need this job, so I will have to somehow get through the interview and potentially deal with working there for ~3 months. 

Any advice or support would be greatly appreciated, please.
