Hi molly909. Welcome to Psych Central. Sorry you feel anxious about your boss asking you to change.

I do not know the answer to your question. My experience in the work place was it was "the longest running show on television" ever. Every day I "acted the part" and managed to survive. Outside of work I was more myself. I did things and talked to people in a more natural style. For me it was a great "acting gig" even though it was in an office and it paid the bills. I had to adapt to what other people felt was appropriate. It was not my boss so much as the needs of the job to modify my behavior.

Think of going to a hospital and the nurses behave according to an unwritten code of behavior. Every work environment has it. Modifying our words and mannerisms so that others can hear us and work with us is important part of professional development in my experience.
