Change....
Mighty Duck,
I think your situation is not new and at some stage in everyone's flying life the 'frustration' does kick in with different event... like not being able to progress quicker, the lack of funds forcing you down and unwanted path or and the dam weather....etc.
Instructors in my books are of two type the ones you can learn from and the ones who can teach!! and this comes down to personal aptitude and alot of attitude (the positive kind I mean) .. In one way or the other everyone's comments out here reflect the same message.
Find an instructor in the school you can be honest with.. don't hesitate to tell them what you think, it's a two way learning curve no matter how old or experienced someone is.. feedback is 'constructive'...if you want it to be! And don't forget its your MONEY at the end of the day.. ask yourself what value do you gain out of the instructors time and was it worth it.... if you don't feel any more confident after trying this approach find another school.
I hope you things go well for you ....
Cheers!
