I need help :/

I'm not exactly sure where to post this (sorry since it's random) but I need help and reassurance. I have my first ever job interview on Wednesday at Applebees and don't know how to go about it... I'm an extremely shy person, awkward, and stutter when faced with things like this so if you can help me prepare for this in anyway possible it would be much appreciated. ❤

Update:

Thank you to those who have answered :) my interview is tomorrow and I thankfully feel a bit better.
