Addressing a crowd as a stutterer

Addressing a crowd as a stutterer So at my work place, my boss knows I stutter yet she wants me to address a group of patients at work by Monday. The last time I spoke in front of a crowd I really wanted to Bury myself in the ground cause I had these blocks and saw people smiled sheepishly because I struggled to let a word out so I felt really embarrassed. I don't stutter so bad but the fact I have anxiety doesn't help. I don't know what to do! Pls help?
