Gyno anxiety

Im a molestation survivor. Going to the gyno is the hardest thing for me. Ive only been once, and that was when I got my implant. I wanted the implant because they told me they wouldnt need to preform a pelvic exam because im 17. I asked multiple times, over and over, and they all reassured me that I wouldnt have to do the exam. When I got back there with the doctor, she did a breast exam and that was ok, but then she said I needed to do a pelvic exam or I couldnt get the implant. I started crying, and the doctor told me to basically get over it. I was crying so hard, I started having a panic attack and I threw up from nervousness. It was an awful experience. I have pcos, and im pretty sure I have severe vaginal dryness that goes along with it. Its so painful and uncomfortable, and im not sure how to treat it. But I cant go to the gyno. Everytime I think about it I start to panic. What can I do?
