I was wondering if anyone could help clarify the difference between PCOS and Cushings?

I have some symptoms of each, but not all the symptoms of either (and my period is completely regular). My cortisol and testosterone levels are really elevated, but the rest of my hormones are fine. And my doctors have found a pituitary tumor (it's to small to be affecting me), and only one ovarian tumor (which isn't growing).

I just don't understand why my doctors aren't taking my hormone problems seriously considering I also have mental health issues.
