Maybe this post
can give some light about the issue.
Well it's not the best situation. On one hand I'm sure the sensei would like to help you but on the other he has a business to run and students to protect.
I think you might just be best waiting it out, John. I don't see much other choice really. Take some time off and relax a bit...read some books.
And when you get back to class try and take it a bit easier and keep the drama away.
Best wishes to you, John. I hope it all works out for you.
