there are too many unanswered (and unanswerable) questions for any of us to give you any reliable feedback. for instance ...
is she actually mean or are you actually insecure and overly sensitive?
is she merely straightforward in order to not waste the time you are paying for?
do you want to be spoonfed and coddled vs taught?
or is she, in fact, an imperious dragon who chose the wrong profession?

we can't know.

have a calm, factual, heart-to-heart discussion with her.
provide clear, accurate examples of the things that bother you.
give her a fair chance to meet you on common, satisfying ground.
