medical anxiety please help

Hi i’m 20f and i have a bit of medical anxiety after being “groomed” (?) but my gyno a few years back. i really need to go back as i am having mental health issues and i know i need treated for them. can someone please just help me out with what i should say to express these concerns? i haven’t gone back to the doctor since my situation which happened when i was 17, so my mom usually helped me, but now that im an adult im lost.i usually just shut down completely and don’t voice how im actually feeling when the time comes. Thanks in advance!
