I just had an interview and it was terrible.

I just had an interview and it was terrible. I was applying to work at an ice skating rink. I stuttered the whole time due to my social anxiety. While I did give long answers and provided examples, I was very nervous due to having family members listening. Should I email the employer about my stuttering problem? The interviewer said she would talk to the manager and get back to me later. Is that a good sign or bad?
