Knowing is better than NOT knowing. Once you know, you know which tool box to break open and what tools to use. As the others have pointed out here, there are meds and treatments to manage things like this.
I know shame is damned difficult to work past - sis and I had to test out as well, we both came back positive for HSV. It's better, in the long run, for yourself, and anyone you might decide to get involved with - if you know already. This way you can manage your symptoms, manage the illness, and possibly prevent the long-term complications that can come from an unmanaged illness of this nature.
It took a lot of strength to seek out and do the testing, bro. You should be proud of yourself for doing that! Take care of you, and follow up with the proffessionals and treatments as they may come.
Adapt. Overcome. Survive.
