Would being diagnosed with Bipolar Disorder keep her from her dream career?

My cousin was recently diagnosed with bipolar disorder, she wants to be a massage therapist like me however on the applications to apply for your official license they now require you to disclose if you've ever been diagnosed with any mental disorder (they didn't used too). I wonder if she can be turned down for her license because of this, even though it's not like she chose to have it though so it's just wrong if they do turn her down. She is taking all of the proper steps to to get better and has been doing wonderfully since. Does anyone have any idea? I call the licensing board but can never get through! Thank you kindly in advance.
