just to play devil's advocate......
some instructors do not know how to give positive feedback to go along with the corrections. it is possible that, to her, she is just advising you of corrections that need to be made. unfortunately she is not doing it in the best way and it comes across as bossy and highly critical. of course, i am not there to see, so you need to decide how much you are willing to put up with. if you are getting good tips and help in increasing your skill you may be willing to go along with her. if you are not increasing skill then you may need to look for another teacher. there is a lot to be said about a "good fit" for personalities. i wish you luck.
