Panicking

Panicking I can't stop crying and shaking, I'm starting a pastry course in 5 days and I've been thinking about the moment where I need to introduce myself since I found out about the course. Im so scared about saying my name, sometimes I can control it and say it smoothy but other times not. When I stutter badly I wanna cut myself and I've been clean for 8 months now. I'm so scared about cutting. I've gone back and forward of the thought of the just have a different name for the course but I really don't know. I just panic at the thought of being asked my name, I'm not sure it matters what name it is. My name is saoirse (pronounced seer-sha) I'm really sad and scared right now and Idk what to do :(
