Do I have a case if after a 30 minute phone interview I was not allowed to work because a doctor diagnosed me with a mental disorder?

I applied and was hired. I was honest about all medical info including my mental illness. Then I was pulled out of orientation for an evaluation. After a 30 minute phone interview their doctor said I had bi polar. I had been hospitalized for borderline personality disorder and depression with suicidal ideations. I was told I would be deemed unfit for duty till i was symptom free. Also that I had to be on what he deemed was appropiate levels of medication. Do I have a case?
