"Very disappointed"

I went in few weeks ago, I needed a scan to be done after a frightful experience. The receptionist was of course very nice and helped me and booked me in and the waiting time was quicker than I expected. However, once I was with the nurse it felt like I was just another teenager coming in with another scare about sexual health. The nurse accused me and my partner about who we had intercourse with after we had broken up, accused one of us lying, and basically put any of points down and was very argumentative. I was very disappointed in this, and my partner was very scared about what was happening with me and my body. We were hoping the scan would be able to clear up a few things and put or minds at rest, as we thought it could be serious. Because of the nurse's approach I have not been back, and therefore I have not had the scan and do not know what is wrong. This is horrible for me as I do not know what is wrong with me and whether it is serious and whether I need medical attention. Please sort this out and ensure all nurses are not like this.
