This forum is not a place to assess HIV risk. This is where we discuss anxiety and OCD. Only. I would talk to your doctor about what is going on with the mental health disorder. Sertraline or Zoloft is a good medication but it normally takes a higher dose to be really effective. And if it isn't working to help you overcome your anxiety, then there are many other options. Talk therapy with a psychologist or counselor is also very beneficial to learn coping skills. You'll never fully get rid of anxiety but it should be more manageable than it currently is. So, treat the anxiety as the disease to be worried about and treat it to its full extent.
