Panic over symptoms and confused by test results

I feel bad admitting this but my anxiety is through the roof. Several years ago I got really drunk and did something extraordinarily stupid and went to a shady massage parlour and had a protected handjob and a condom protected blowjob. I waited more than 6+ months and took the panel of std tests and all negative, including HSV 1 and 2 IgG Ab which were < 0.2. I've done nothing since then, abstaining perfectly. Two years ago I had a small swath of blisters on my outer left thigh. I ignored it and it eventually healed and went away. Suddenly earlier this week I had a larger patch, which looks like a long brush stroke of blisters, near the same location, as well as my upper left groin in a similar long brush stroke form.

I went to the doctor who said it looks like Shingles and did a HSV 1 and 2 swab test. I get the results tomorrow and I am trying to pull myself out of an ongoing anxiety attack over this. I am in my late 40s, almost 50. With that very low risk encounter years ago plus the negative IgG tests, I'm assuming the odds that this is actually shingles are high. However, it also seems really unusual that it would happen in roughly the same place twice, although more than two years apart.

Has anyone else experienced anything like this? What should I expect? Of course I asked AI and one said it's highly unlikely to be HSV but that I need the PCR test results to confirm, and the other AI I asked said it's extremely unlikely to be HSV given my past low risk encounter and negative tests back then. Any tips to managing my anxiety while I wait for the results?
