Paranoia??? Or herpes

I had unprotected sex with someone back in March. I trusted the guy and he recently got tested and was all clean. For the past two months I have experienced nothing but paranoia and anxiety over this and have gotten tested for STD’s 4 times. I have no signs or symptoms of herpes and everyone has told me to calm down. However, for the past 2-3 days my vagina has been tingling non-stop. Does anyone know whats happening to me?? Or is this also anxiety?
