Have a job interview Wednesday... Thinking about canceling

Have a job interview Wednesday... Thinking about canceling I'm currently in my second year of college. I realized that I needed to start getting some experience to put on my resume for after I graduate, so I sent in some applications to a few entry level jobs that interested me. I was fine with everything until I was sent a response from one employer asking to do an interview. I've come a long way with my stutter the past year and am a lot more confident with my speech, but I just don't think I'm ready for this yet. Does anyone have any experience with situations like this? Any advice you guys can give me? Edit: Thanks for all the positive responses everyone. I still feel really uneasy about this, but that's not something that's ever going to change. I'm going to have to go to a job interview at some point in the future, so I may as well get it over with. I really appreciate all the positive support. You all made it a bit more bearable. :)
