A big thank you to everyone who took the time to answer my posts. All the replies have helped me get enough confidence to realise that I don't really deserve this kind of treatment.
So I just thought that I'd post a quick update. I still go to his class but only once a week A few weeks ago, a 1st Kyu that I had never met before (he's been off with an injury) came to class. He's also privileged enough to get the same sort of treatment from our instructor as I do. We've sort of started our own remedial class in a corner. It's also nice to know that it's not just me. So that's an improvement.
I have also looked around and found another school that is associated with my club. I go to that once a week. It's a real trek from where I live but worth every hour I spend travelling.
It's hard to explain how rejuvenated my interest/love for Karate has become over the last couple of weeks.
Thanks again for all the advice,
