I quit my job. I thought I could handle it because lately I could keep my social anxiety under control, but after yesterday I realized i should probably have a slower job first. I told my shift manager that I had to quit because my social anxiety and everything, and he said that he understands and I could use him as a reference.

He also mentioned that they shouldn't have put me out on the floor on the weekend(most busy time) only on my third day, and he agreed with me that i should maybe take a slower job.
