STD contamination fears

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.

A few days ago, I posted how proud I am of myself, that I managed to go to the doctor to get a vaccination. Now, two days later, I find myself panicking and ruminating. It was a practice where they also test a lot for HIV and other blood diseases and in my mind, the needle/syringe they used for my vaccination was somehow contaminated with blood from another patient. Maybe by accident but sometimes my mind would make up a scenario where they would do it even on purpose. I was so proud of myself, that I managed to go there on Monday and now I am making up scenarios how I caught HIV by going there - I am feeling guilty because I was „careless“. Any tips for the moment? ❤️

As the title says, I’m having a severe breakout while abroad with a friend. It is contamination related and mostly STI related. I am at loss what to do and that ehat I’ve learned I am not able to follow and my intrustive thoughts are going rampant. I am not able tk enjoy my time and I am faking it for my friend. Going back earlier is not an option. What can I do to survive this period? I am not able to distinguish realistic fears from unrealistic ones anymore
