Scared to teach tomorrow

I have some social phobia, though I don't know if I have the full blown disorder.

Tomorrow I teach (adults) in a new school and I am freaking terrified. I can see this going either way. Depends on the student body. Social anxiety/performance anxiety is SO uncomfortable. I teach in another school as well, and knowing I'm well-liked there and I've taught the class a hundred times it's really easy. But in that school they're really made to respect the teacher. Other schools I have not found that so much. So although I'm knowledgeable about the subject matter, I'm nervous that b/c I'm new to the school and might come across as nervous I'll get a hard time. Afraid I'll mess up some how.

Anyway wish me luck.
