Maybe tell her that meditation isn't all you need ?.. you need tools to help you navigate the ups and downs of bipolar.
Hell If meditation was a cure all for Bipolar she would be out of a job and the big Pharma's would crumble and blow away.
Remember YOU are seeking help and that's a really hard thing to do in my opinion.. Get the help you need and deserve ..
If she is unable to provide you the Therapy that will help you move forward and cope better ... It's time to find a new Therapist.
Good Luck
