Anxious ab HIV

So everything has been going well recently. The only thing pressing is for peace of mind I am getting STD tested on Wednesday morning and I am pretty anxious about what the result will say. I go to certain massage parlors that offer extras. And I have made a point to not engage in intercourse but other non-intercourse things I have done. I was afraid that since those women do other things with people that maybe virtual things were left on the beds I would lay down on or something. I told this to a doctor I saw recently and they said it was highly unlikely. But I still have the health worry. But we will see come Wednesday. The only reason I am going is because I went to the urologist and they wanted me to rule things out since I had what seemed like a UTI but it turned out to not be the case. What's a good way to not focus on catastrophizing the situation. I keep worrying that my life is over if I am diagnosed with something and my future relationships will be tainted or I'll put someones health in jeopardy

This fear keeps coming back and it’s to the point I cry and what to panic. I no longer talk to the man simply because I wanted to move on and find something meaningful to have with someone (relationship wise). I still keep fearing I need to go get my blood checked. Thoughts like “what if I have it and don’t know it and give to someone?” “What if that urine test I took months ago didn’t work” I got tested for stds but it came back negative. They took a urine test but google says you have to have your blood drawn!! I’m so scared. My mind tells me “you have HIV” and then a sense of peace comes and scares me even more!!!

In September I had unprotected oral sex. I haven’t had sex in five years because even before that I was so ashamed and worried about sex. I finally did it and then a few weeks later while I was at work I started to be very itchy all in my underwear area like up to my butt. I didnt see any blisters or anything but when I googled it, herpes came up. Eventually I thought maybe it was the new underwear I bought and it went away after I stopped wearing them. However it’s returned twice, mostly when I’m really worried about herpes. I know this makes little sense because I don’t thinking about it would cause an outbreak but, either way I’m really nervous to go get tested because I heard there’s a high false positive rate and if I get a positive there’s a huge chance I will just become a recluse and never speak to anyone again. I already have so much trauma with sex, vaginismus, etc. I can’t imagine telling anyone I have herpes and then they 1) don’t want to be with me 2) now know this and could tell anyone they want Even if I don’t have it I was reading it could be asymptomatic and 80% of people who have it don’t even know, so now I’m worried I will get it no matter what sex I have. I can barely handle staying alive with just OCD but now with social stigma with herpes I will feel like I can not even live a normal life. I am already freaking out about it and don’t know what to do. I am worried to go get tested and it saying I have it, and then I’m worried to not and potentially spread it, I’m not even having sex with anyone right now so it’s not like I would. But I’m worried I will forget to wash my hands and touch something and someone else will touch it and then get it. I’m just having a really bad time.
