Std testing tomorrow!

So I get the regular testing every year with my pap and never had anything come back. I got the full on testing four years ago after my divorce of everything including hiv and all those. I decided to go get retested tomorrow. I Am freaking out! I have no symptoms but I don't know the relief of knowing I don't have anything feels good. It's been a few years since I was tested for HIV... All the others I get tested yearly but like I said I am choosing to get tested tomorrow... Prayer please! I am really nervous and freaking out! Plus I do have a question how often should you get a ste screening? I mean ALL THE STDS from the clap to  hiv testing.... Yearly? I am in a serious relationship but like I said I like to know. Makes me feel better.... Aniexty at its worse I know.
