i have severe anxiety when i need to introduce myself in social situations. advice?

i have severe anxiety when i need to introduce myself in social situations. advice? 90% of the time i stutter its when i have to introduce myself, specifically when i have to say my name. the rest of the time i'm well off. This however causes me to have anxiety sometimes months before i know such a situation will occur. I was worried that i wouldn't be able to say my name at my first day of work months before it even happened. Does anyone else here have this particular block and how do you deal with it? i find it so annoying that i'm able to talk normally to almost anyone and have come to accept my stutter as part of me but when it comes to saying my name i'm back to my old diffident self
