If my only risky behavior was kissing should i stop worrying?

please help im having a panic attack. i made out 2 months ago with someone who i later found out has some behaviors that make them higher risk for hiv. i know there is a theoretical risk of ping it this way, but this is my only risk other than one other ual experience 5 years ago with a virgin girlfriend. I know believe i have the beginning stages of shingles which is very rare in non hiv patients my age (im 22). i cant stop researching the internet and panicking i must have already spent like 20 hours online. Im to worried to get the test i cant do it i even went to the clinic but backed out. what should i do?
